Our professor teased us that there is a way, in languages that have xor operators, to switch two variables without introducting a temporary variable. I can't figure out how to do it. Can anyone here?

And, to clarify, xor is true if either A or B is true, but not both. I'm not clear how it relates to the problem though, since I'm imagining that A and B can be any type of values...

Thanks for any pointers. Now I'm really rather curious. :-).
