thanks for the patch

so far with current code I can find all functions, and their respective
parameters. for function body there is CPlusPlus::Block.
question now is: how can I find local variables declarations within this
Block? how can I visit AST of this Block? (there always is body as compound
statement or similar.)
How can I retrieve this compound statement within Block? I know you are
somehow doing this in checks / code completion but I could not find this in
the code

Thanks

Marek
