It's impossible to bind every symbol reference without expanding mixins and templates (which may require CTFE). I think reusing DMD's code here might work better than reinventing the wheel, especially as it'll pick up bug fixes, etc.

That's exactly why I'm betting on DMD's semantic code.

It's amazing the number of gotos Walter uses. But, amazingly, all of 
them just are for one reason: not to duplicate (even a single line of) code.

I think he ment the Reference class.
