string demangle(string name);
  Demangle D mangled names.
  If it is not a D mangled name, it returns its argument name.

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

      import core.stdc.stdio : stdin;
      import std.stdio;
      import std.ascii;
      import std.demangle;

      void test(int x, float y) { }

      int main()
      {
          string buffer;
          bool inword;
          int c;

          writefln("Try typing in: %s", test.mangleof);
          while ((c = fgetc(stdin)) != EOF)
          {
              if (inword)
              {
                  if (c == '_' || isAlphaNum(c))
                      buffer ~= cast(char) c;
                  else
                  {
                      inword = false;
                      write(demangle(buffer), cast(char) c);
                  }
              }
              else
              {   if (c == '_' || isAlpha(c))
                  {
                      inword = true;
                      buffer.length = 0;
                      buffer ~= cast(char) c;
                  }
                  else
                      write(cast(char) c);
              }
          }
          if (inword)
              write(demangle(buffer));
          return 0;
      }
