[Qt-creator] ASTVisitor callback

[Roberto Raggi]

Hi,

Yes, we will have something like that, but you need to be a bit more  
patient. We are still working on the C++ front-end, and updating all  
the visitors after we introduce (or change) an AST node is 1) a lot of  
work 2) boring 3) it's pretty easy to introduce regressions. So we  
will provide custom AST processors as soon as the API for the C++  
front-end is a bit more stable.

ciao robe
