To be perfectly clear, I think this was a really interesting and  
useful discussion.  The only reason I'm pushing back so hard is that  
we already have lots of concrete problems to solve.  I think we should  
only pursue this sort of thing in the future, if/when the lack of this  
capability is blocking something.

That said, I would strongly support changes to split up actions/sema  
somehow (as long as we don't lose performance or clarity of the  
code).  To me, it would be ideal if we could split up Sema into  
different modules somehow based on purpose (types, decls, expr/stmts, c 
++, objc, etc) rather than split up each individual action callback.
