In case of Clang (and more specifically libClang,) I am usually using it to do source-to-source translations on C++ code. In those cases, sometimes I need some fairly advanced knowledge, such as the type of an expression, to match on or perform logic on. However, this still looks quite interesting for some use cases (and I am interested in such tools.)
