You're not wrong :)
The problem is that the foreach variable is not evaluatable to a 
compile-time string. I don't know why, but I'll figure it out tonight.

I've also managed to convert an enum to an AssocArrayLiteralExp* (with the 
name/string as the key and the value/int as the value) but it seems that it 
cannot be foreached at compile time, even if it's a literal expression. But 
hell, I've spent about 1 hour browsing through dmd's code, so I'm pretty 
sure it's possible with a little more research.

I want to get either one to work at compile-time. In the case of TupleExp, 
one could then use a string mixin to convert the string to a value.


* I don't have the AA patch handy (I'm at work) but it's a good exercise: 
start with my original tupleof patch but create an AssocArrayLiteralExp 
instead of the TupleExp. You'll need two Expressions arrays, one for keys 
and one for values. EnumMember::ident is the name, EnumMember::value is the 
value expression. Pretty straightforward.
