StorageClass `mergeFuncAttrs`(StorageClass `s1`, FuncDeclaration `f`);
  Merge function attributes pure, nothrow, @safe, @nogc, and @disable
FuncDeclaration `hasIdentityOpAssign`(AggregateDeclaration `ad`, Scope* `sc`);
  Check given aggregate actually has an identity opAssign or not.
  Parameters:

  AggregateDeclaration `ad` | struct or class
  Scope* `sc` | current scope

  Returns:
  if found, returns FuncDeclaration of opAssign, otherwise `null`
FuncDeclaration `buildOpAssign`(StructDeclaration `sd`, Scope* `sc`);
  Build opAssign for struct. ref S opAssign(S s) { ... }
  Note that s will be constructed onto the stack, and probably copy-constructed in caller site.
  If S has copy copy construction and/or destructor, the body will make bit-wise object swap: S _swap = this; // bit copy this = s; // bit copy _swap.dtor(); Instead of running the destructor on s, run it on tmp instead.
  Otherwise, the body will make member-wise assignments: Then, the body is: this.field1 = s.field1; this.field2 = s.field2; ...;
bool `needOpEquals`(StructDeclaration `sd`);
  We need an opEquals for the struct if any fields has an opEquals. Generate one if a user-specified one does not exist.
FuncDeclaration `hasIdentityOpEquals`(AggregateDeclaration `ad`, Scope* `sc`);
  Check given aggregate actually has an identity opEquals or not.
FuncDeclaration `buildOpEquals`(StructDeclaration `sd`, Scope* `sc`);
  Build opEquals for struct. const bool opEquals(const S s) { ... }
  By fixing https://issues.dlang.org/show_bug.cgi?id=3789 opEquals is changed to be never implicitly generated. Now, struct objects comparison s1 == s2 is translated to: s1.tupleof == s2.tupleof to calculate structural equality. See EqualExp.op_overload.
FuncDeclaration `buildXopEquals`(StructDeclaration `sd`, Scope* `sc`);
  Build __xopEquals for TypeInfo_Struct static bool __xopEquals(ref const S p, ref const S q) { return p == q; }
  This is called by TypeInfo.equals(p1, p2). If the struct does not support const objects comparison, it will throw "not implemented" Error in runtime.
FuncDeclaration `buildXopCmp`(StructDeclaration `sd`, Scope* `sc`);
  Build __xopCmp for TypeInfo_Struct static bool __xopCmp(ref const S p, ref const S q) { return p.opCmp(q); }
  This is called by TypeInfo.compare(p1, p2). If the struct does not support const objects comparison, it will throw "not implemented" Error in runtime.
FuncDeclaration `buildXtoHash`(StructDeclaration `sd`, Scope* `sc`);
  Build _xtoHash for non-bitwise hashing static hash_t xtoHash(ref const S p) nothrow @trusted;
FuncDeclaration `buildPostBlit`(StructDeclaration `sd`, Scope* `sc`);
  Create inclusive postblit for struct by aggregating all the postblits in postblits[] with the postblits for all the members. Note the close similarity with AggregateDeclaration::buildDtor(), and the ordering changes (runs forward instead of backwards).
FuncDeclaration `buildDtor`(AggregateDeclaration `ad`, Scope* `sc`);
  Create inclusive destructor for struct/class by aggregating all the destructors in dtors[] with the destructors for all the members. Note the close similarity with StructDeclaration::buildPostBlit(), and the ordering changes (runs backward instead of forwards).
FuncDeclaration `buildInv`(AggregateDeclaration `ad`, Scope* `sc`);
  Create inclusive invariant for struct/class by aggregating all the invariants in invs[]. void __invariant() const [pure nothrow @trusted] { invs[0](), invs[1](), ...; }
