Try `!x != !(y & z)', which gets the same results; if the operands are
booleans to begin with, you can leave out the unary !s.

"^^" is a perennial suggestion which really has very little to recommend
it.  It can't short-circuit like && and ||, because XOR has to evaluate
both operands.  And it would be useful rather rarely.
