1. What about `__PRETTY_FUNCTION__` ?
2. Consider following generic error handling macro:

(ThrowException is some template function)

  #undef STR
  #define STR(a) XSTR(a)
  #define ThrowExceptionHelper(CLASS, fmt, ...) ThrowException<CLASS>(__FILE__ ":" STR(__LINE__) ": %s: " fmt, __PRETTY_FUNCTION__, ##__VA_ARGS__)

Which is called like `if(somethig) ThrowException(std::exception, "%s", "bar");`
Even though the function name may be useless, file/line info is still there and is(?) correct.
Perhaps there should not be a warning in such a case?
