Go compiler!

[Simen Haugen]

dmd crashes with stack overflow, and I finally figured out the problem : 
Forward references...

It's certainly not the first time I've hit these bugs (or a bunch of other 
bugs - all known), and it's often quite hell to work around.

I really like D, and have used it a lot recently, but all the bugs are 
getting on my nerves. My first wish for d is to get a stable compiler. I 
think this is a lot more important than working on d2

Just needed to get some frustration out before I start refactoring...
