Source std/demangle.d

pure nothrow @safe string `demangle`(string `name`);
  Demangle D mangled names.
  Parameters:

  string `name` | the mangled name

  Returns:
  A string. If it is not a D mangled name, it returns its argument name.
  Examples:

      // int b in module a
      writeln(demangle("_D1a1bi")); // "int a.b"
      // char array foo in module test
      writeln(demangle("_D4test3fooAa")); // "char[] test.foo"

  Examples:
  This program reads standard in and writes it to standard out, pretty-printing any found D mangled names.

      import std.ascii : isAlphaNum;
      import std.algorithm.iteration : chunkBy, joiner, map;
      import std.algorithm.mutation : copy;
      import std.conv : to;
      import std.demangle : demangle;
      import std.functional : pipe;
      import std.stdio : stdin, stdout;

      void main()
      {
          stdin.byLineCopy
              .map!(
                  l => l.chunkBy!(a => isAlphaNum(a) || a == '_')
                        .map!(a => a[1].pipe!(to!string, demangle)).joiner
              )
              .copy(stdout.lockingTextWriter);
      }
