Agreed. I had a feeling we'd need to separate type checking from  
implicit init list construction.

No worries. Since you/I worked on CheckInitializerListTypes, it's  
really good to have you review/enhance CheckInitList. I find this part  
of the C language very tricky. fyi...I'm in the process of moving my  
family and Apple's World Wide Developers conference is coming up soon  
(as a result, CheckInitList hasn't received my attention for a couple  
weeks now).

I noticed this patch doesn't enable any of these changes yet (i.e. you  
didn't change Sema::CheckInitializerTypes()). Was this intentional?

I haven't reviewed the patch closely, however I think it moves the  
ball forward. Please commit (and we can iterate if necessary...).

Thanks again - I greatly appreciate the work you are doing!
