[cfe-dev] lookup from AST

[steve naroff]

Hi Axel,

Sema is considered a transient object (whose 'output' is a well-formed  
AST).

The design is oriented toward creating an ASTConsumer. This 'callback'  
interface, combined with ASTContext's "get*" functions (and the  
respective AST's) should do the trick.

Did you try this? If we are missing some functionality in the AST, let  
us know (it is entirely possible that there is some logic that needs  
to move from Sema->AST).
