No, what Adrien has is sufficient to traverse statements as well. 
TraverseDecl(tu_decl) will traverse the entire AST, which includes 
statements and expressions. That's why you have the RecursiveASTVisitor: 
it figures out how to visit all of the subchildren for you so you just 
have to worry about implementing VisitStmt and figuring out what to do 
on all of the statements in the file.
