You got to give it to Walter: the code is pretty clean (for C++ code anyway)

Add the attached code to src\dmd\mtype.c, line 5025 (in 
TypeEnum::dotExp, after the #endif). This now works:

import std.stdio;
enum ABC { A, B, C };

void main(string[] args)
{
   foreach(a; ABC.tupleof)
   {
     writefln(a);
   }
}

prints:
A
B
C

Of course, I'm way over my head here. I've just copied the code from 
struct.tupleof to make enum.tupleof and creating a tuple of StringExps 
insteadof DotVarExps, whatever they are....
