Real Programmers need no special syntax :)

   import std.stdio;

   void foo(int a){ writeln("overload int"); }
   void foo(long b){ writeln("overload long"); }

   auto pickOverload(alias FP, A...)() @property { typeof(FP(A.init)) function(A) fp = &FP; return fp;}

   void main()
   {
       auto b = pickOverload!(foo, long);
       b(2);
   }

But using the context to automatically figure out the right
overload make some things easier; it's just that eg the lhs of
an assignment affecting the result of the rhs-expression doesn't
/feel/ right.
