That's what I'd been doing for findFunctionDef() findExpr().
My problem was, if calling findStemnt() from main without
calling either of the other 2 callbacks, I couldn't figure out how to
tell which function the statement was part of (that's where I thought
the info would be somewhere in the symbol table of the statement. is it
there? this is not an essential question, since i've solved my problem
for now, just curiosity as i didn't find it easily).

Now that i'm getting my head around c++ and oo I've realised I can use
findFunctionDef() and cast its FunctionDef parameter to a Block which
then gives me access to the findStemnt() callback.

so sorry, it was a case of still figuring out how it all holds
together..

thanks for the quick answer!
