Hey Ted,

What's the benefit of unifying them? (other than removing some API/ 
code).

Having two separate table's that model the C/ObjC namespaces may be  
better from a lookup perspective (fewer hash collisions). There may be  
some size reduction I imagine (however I believe it would be quite  
small).

Unless you see a performance win, I'm not sure fiddling with this  
level of clang is important (for now, at least).

My 2$,
