I stand corrected.

As Thorsten ever so politely pointed out, a ^ b works just fine, and is 
logically equivalent to my original suggestion.

I knew of & and | as the non-short-circuit versions of && and ||, but I 
didn't know that ^ was a valid operator on booleans.
I only knew of ^ as a bit-wise operator on numerical primitives before.
