(Operators) infix ?^ §
multi sub infix:<?^>(Mu = Bool::False)multi sub infix:<?^>(Mu \a, Mu \b)Boolean logical XOR operator. Coerces the argument(s) to Bool and performs logical XOR on it(them): it will return True if and only if just one of the argument is True. On a single argument it behaves as identity, returning the coerced value.
