This is very interesting. I don't understand the example though (some is 
commented out, some is in, and I'm unclear on what didn't use to work 
and what works). Also I can't find the important commits in your branch, 
so it may be best to organize those as one pull request for the dmd 
mainline.

Could you please provide more detail on what you fixed and what the 
resulting context is?


Thanks,

Andrei
