But isn't there a few language constructs the specifically rely 
on the GC? I thought this was the whole issue of not being able 
to disable the GC completely in dmd? If so, the core language 
spec would have to be designed to be GC agnostic.

I think the ability to mark a module with attributes would help. 
Possibly extend UDA's to work on the module keyword also.
