Wrong value returned from xor function in fandango module

[John-James-Rambo]

In some cases functional.xor function returns boolean instead of argument.

from fandango import functional
functional.xor(0, 2)

returns 2 but:

from fandango import functional
functional.xor(2, 0)

returns True

from fandango import functional
functional.xor(2, 2)

returns False
