[cfe-dev] determine scope in a RecursiveASTVistor

[ret val]

While Looking at function pointer declarations with a RecursiveASTVistor I'm
trying to keep track of their scope.

My original plan was to delimit scope based on Entering/Leaving a
CompoundStmt since it looks like its a nice logical grouping, but I noticed
in the Doxygen docs nothing inherits this class. I was expecting functions
and loops to inherit this.

So now I'm wondering what a good way to go about this is, hopefully still
using a RecursiveASTVistor.

Thanks
