I had an even more horrid dmd crash some time ago, removing a circular selective import seemed to fix it. But I'm not sure and can't replicate it any more :(

Done.
Ah, ICE = Internal Compiler Error :)
And, format isn't a CTFE-function?

Could you maybe also help me with this one?

enum E { A = 0, B, C }
char[] _mixin(int i) {
  return "e = " ~ (cast(E)i).stringof ~ ";";
}
void main() {
  E e;
  mixin( _mixin(1) );
} 
// Error: type E is not an expression

I just want to use a var to index an enum and then get its .stringof :)
