I don't think it's a bug. Unless you want to sprinkle lots of code with
type tests, the result is whatever the implementation says, in this case:
xor: aBoolean
"Exclusive OR. Answer true if the receiver is not equivalent to aBoolean."
^(self == aBoolean) not
You could equally complain about
true & "anything"
answering the argument instead of raising an error.
Cheers,
