Would be nice if compiler gave more information!

I can't because I have no idea what causes it. I changed the 
mixin to not use the foreach but a CTFE that generates a string 
using the foreach which is then mixed in.


Why can't the compiler give a stack trace? Any information is 
better than none!

I am getting the compiler to crash from a different problem after 
I moved some files around. I have no idea where the error is now.

Why not ship with a debuggable dmd so that when it crashes it can 
be debugged and potentially fixed but at least see where it might 
be crashing.
