They would still be the same object - so would continue to compare equal 
and have the same identity. What I'm suggesting is similar to how Python 
3 treats the use of super - and that is compile different code when you 
call str(...) from when you call unicode(....) - only when you use those 
literal identifiers in source code.

Any use of them other than calling them directly would continue to 
behave as IronPython does currently.

Well, like aliasing super in Python 3, with my suggestion that would 
then be broken (or at least would fall back to standard str behaviour). 
As this is uncommon anyway it shouldn't break *much* code.

All the best,
