Hmm, I wouldn't consider renaming a function a simple transformation, really. Consider overloading. You have to do full overload resolution (one of the most complex things in C++) in order to figure out whether a name in a given function call needs to be changed or not.
Renaming the function is simple. Ensuring that you're avoiding name conflicts can be more difficult. Propagating the change requires a lot more work. It's also requires knowledge beyond what a compiler can give you since changes may be required in multiple translation units. Andrew Sutton asutton@cs.kent.edu
