What is the correct solution then? To put branches all over the code of the checkers? Surely not. The checker must first recognize the nature of the iterator parameters and return values for every call. This recognition and then the decision should be wrapped into a function. If not in `CallEvent` then in the iterator-related checker's common library. There is no point to repeat the same code all over the checkers.
