#### Linker Changes

List of all bug fixes and enhancements in D 2.066.

#### Compiler Changes

1. -w now warns about an unused return value of a strongly pure nothrow function call:

   A discarded return value from a strongly pure nothrow function call now generates a warning.

       int foo() pure nothrow { return 1; }
       void main()
       {
           foo();  // the result of foo() is unused
       }

   With the -w switch, the compiler will complain:

       Warning: calling foo without side effects discards return value of type int, prepend a cast(void) if intentional

2. -noboundscheck has been deprecated in favor of boundscheck=[on|safeonly|off]:

   Confusion over what the -noboundscheck command line option did led to the creation of the new option -boundscheck=[on|safeonly|off] which aims to be more clear while enabling more flexibility than was present before.

   -boundscheck=

   - on: Bounds checks are enabled for all code. This is the default.
   - safeonly: Bounds checks are enabled only in @safe code. This is the default for -release builds.
   - off: Bounds checks are disabled completely (even in @safe code). This option should be used with caution and as a last resort to improve performance. Confirm turning off @safe bounds checks is worthwhile by benchmarking.

   Use -boundscheck=off to replace instances of -noboundscheck.

   Prior to this there was no way to enable bounds checking for -release builds nor any way of turning off non-@safe bounds checking without pulling in everything else -release does.

3. -vgc was added to list GC allocation code positions in the code:

   Prints all GC-allocation points. Analysis will follow the semantics of the new @nogc attribute.

4. -vcolumns was added to display column numbers in error messages:

   Diagnostic messages will print the character number from each line head.

       int x = missing_name;

   Without -vcolumns:

       test.d(1): Error: undefined identifier missing_name

   With -vcolumns:

       test.d(1,9): Error: undefined identifier missing_name

5. -color was added to make console output colored:

   Errors, deprecation, and warning messages will be colored.

#### Language Changes

1. @nogc attribute was added:

   @nogc attribute disallows GC-heap allocation.

       class C {}
       void foo() @nogc
       {
           auto c = new C();   // GC-allocation is disallowed
       }

2. extern (C++, namespace) was added:

   To represent a C++ namespace, extern (C++) now takes optional dot-chained identifiers.

       extern (C++, a.b.c) int foo();

   is equivalent with:

       namespace a {
         namespace b {
           namespace c {
             int foo();
           }
         }
       }

3. Operator overloading for multi-dimensional slicing was added:

   Documentation is here.

   Example code:

       struct MyContainer(E)
       {
           E[][] payload;

           this(size_t w, size_t h)
           {
               payload = new E[][](h, w);
           }

           size_t opDollar(size_t dim)()
           {
               return payload[dim].length;
           }

           auto opSlice(size_t dim)(size_t lwr, size_t upr)
           {
               import std.typecons;
               return tuple(lwr, upr);
           }

           void opIndexAssign(A...)(E val, A indices)
           {
               assert(A.length == payload.length);

               foreach (dim, x; indices)
               {
                   static if (is(typeof(x) : size_t))
                   {
                       // this[..., x, ...]
                       payload[dim][x] = val;
                   }
                   else
                   {
                       // this[..., x[0] .. x[1], ...]
                       payload[dim][x[0] .. x[1]] = val;
                   }
               }
           }
       }
       void main()
       {
           import std.stdio;

           auto c = MyContainer!int(4, 3);
           writefln("[%([%(%d%| %)]%|\n %)]", c.payload);
           // [[0 0 0 0]
           //  [0 0 0 0]
           //  [0 0 0 0]]

           c[1 .. 3,
             2,
             0 .. $] = 1;
           /*
           Rewritten as:
           c.opIndexAssign(c.opSlice!0(1, 3),
                           2,
                           c.opSlice!2(0, c.opDollar!2()));
           */

           writefln("[%([%(%d%| %)]%|\n %)]", c.payload);
           // [[0 1 1 0]
           //  [0 0 1 0]
           //  [1 1 1 1]]
       }

4. __traits(getFunctionAttributes) was added:

   This can take one argument, either a function symbol, function type, function pointer type, or delegate type. Examples:

       void foo() pure nothrow @safe;
       static assert([__traits(getFunctionAttributes, foo)] == ["pure", "nothrow", "@safe"]);

       ref int bar(int) @property @trusted;
       static assert([__traits(getFunctionAttributes, typeof(&bar))] == ["@property", "ref", "@trusted"]);

5. Support template parameter deduction for arguments with a narrowing conversion:

   Implicit Function Template Instantiation will now consider a narrowing conversion of function arguments when deducing the template instance parameter types.

       void foo(T)(T[] arr, T elem) { ... }
       void main()
       {
           short[] a;
           foo(a, 1);
       }

   In 2.065 and earlier, calling foo(a, 1) was not allowed. From 2.066, T is deduced as short by considering a narrowing conversion of the second function argument 1 from int to short.
6. Read-Modify-Write operations on shared variables are now deprecated:

   Examples:

       shared int global;
       void main()
       {
           global++;       // deprecated
           global *= 2;    // deprecated
       }

   Instead you should use atomicOp from core.atomic:

       shared int global;
       void main()
       {
           import core.atomic;
           atomicOp!"+="(global, 1);
           atomicOp!"*="(global, 2);
       }

7. Support uniform construction syntax for built-in scalar types:

   Examples:

       short n1 = 1;
       auto n2 = short(1); // equivalent with n1, typeof(n2) is short

       auto p1 = new long(1);                  // typeof(p1) is long*
       auto p2 = new immutable double(3.14);   // typeof(p2) is immutable(double)*

   The constructor argument should be implicitly convertible to the constructed type.

       auto n1 = short(32767); // OK
       auto n2 = short(32768); // Not allowed, out of bounds of signed short -32768 to 32767

#### Library Changes

1. Duration.get and its wrappers have been deprecated in favor of the new Duration.split:

   Duration.get and its wrappers, Duration.weeks, Duration.days, Duration.hours, and Duration.seconds, as well as Duration.fracSec (which served a similar purpose as Duration.get for the fractional second units) have proven to be too easily confused with Duration.total, causing subtle bugs. So, they have been deprecated. In their place, Duration.split has been added - and it's not only very useful, but it does a great job of showing off what D can do. Whereas Duration.get split out all of the units of a Duration and then returned only one of them, Duration.split splits out a Duration into the units that it's told to (which could be one unit or all of them) and returns all of them. It has two overloads, both which take template arguments that indicate which of the units are to be split out. The difference is in how the result is returned. As with most of the templates in core.time and std.datetime which take strings to represent units, Duration.split accepts "weeks", "days", "hours", "minutes", "seconds", "msecs", "usecs", "hnsecs", and "nsecs". The first overload returns the split out units as out parameters.

       auto d = weeks(5) + days(4) + hours(17) + seconds(2) + hnsecs(12_007);
       short days;
       long seconds;
       int msecs;
       d.split!("days", "seconds", "msecs")(days, seconds, msecs);
       assert(days == 39);
       assert(seconds == 61_202);
       assert(msecs == 1);

   The arguments can be any integral type (though no protection is given against integer overflow, so unless it's known that the values are going to be small, it's unwise to use a small integral type for any of the arguments). The second overload returns a struct with the unit names as its fields. Only the requested units are present as fields. All of the struct's fields are longs.

       auto d = weeks(5) + days(4) + hours(17) + seconds(2) + hnsecs(12_007);
       auto result = d.split!("days", "seconds", "msecs")();
       assert(result.days == 39);
       assert(result.seconds == 61_202);
       assert(result.msecs == 1);

   Or if no units are given to the second overload, then it will return a struct with all of the units save for nsecs (since nsecs would always be 0 when hnsecs is one of the units as Duration has hnsec precision).

       auto d = weeks(5) + days(4) + hours(17) + seconds(2) + hnsecs(12_007);
       auto result = d.split();
       assert(result.weeks == 5);
       assert(result.days == 4);
       assert(result.hours == 17);
       assert(result.minutes == 0);
       assert(result.seconds == 2);
       assert(result.msecs == 1);
       assert(result.usecs == 200);
       assert(result.hnsecs == 7);

   Calling Duration.get or its wrappers for each of the units would be equivalent to that example, only less efficient when more than one unit is requested, as the calculations would have to be done more than once. The exception is Duration.fracSec which would have given the total of the fractional seconds as the requested units rather than splitting them out.

       // Equivalent to previous example
       auto d = weeks(5) + days(4) + hours(17) + seconds(2) + hnsecs(12_007);
       assert(d.weeks == 5);
       assert(d.days == 4);
       assert(d.hours == 17);
       assert(d.minutes == 0);
       assert(d.seconds == 2);
       assert(d.fracSec.msecs == 1);
       assert(d.fracSec.usecs == 1200);
       assert(d.fracSec.hnsecs == 12_007);

   It is hoped that Duration.split will be less confusing and thus result in fewer bugs, but it's definitely the case that it's more powerful. It's also a great example of D's metaprogramming capabilities given how it splits out only the requested units and even is able to return a struct with fields with the same names as the requested units. This on top of being able to handle a variety of integral types as arguments. And its implemenation isn't even very complicated.
2. Some built-in type properties have been replaced with library functions:

   Built-in array properties dup and idup were replaced with (module-scoped) free functions in the object module, thanks to D's support of Uniform Function Call Syntax.

   Built-in associative array properties rehash, dup, byKey, byValue, keys, values, and get were also replaced with free functions in the object module.

3. Associative array keys now require equality rather than ordering:

   Until 2.065, opCmp was used to customize the comparison of AA struct keys.

       void main()
       {
           int[MyKey] aa;
       }

       struct MyKey
       {
           int x;
           int y;  // want to be ignored for AA key comparison

           int opCmp(ref const MyKey rhs) const
           {
               if (this.x == rhs.x)
                   return 0;

               // defined order was merely unused for AA keys.
               return this.x > rhs.x ? 1 : -1;
           }
       }

   From 2.066, the AA implementation has been changed to use the equality operator (==) for the key comparison. So the MyKey struct should be modified to:

       struct MyKey
       {
           int x;
           int y;  // want to be ignored for AA key comparison

           int opEquals(ref const MyKey rhs) const
           {
               return this.x == rhs.x;
           }
       }
