Pretty sure he meant boolean (nil/non-nil) xor, not bitwise xor.

Some naïve suggestions:

* Call it `xor', to go with `and' and `or'
* Make it n-adic, taking at least 1 argument (since the operation has no 
* Make it a function, so that it can be used with `apply' etc.
* Give it a compiler macro, for efficient partial application

There is probably already something like this in CL, like everything else.
