Camel, ed. 2, pg. 94:

  There is also a logical B<xor> operator that has no exact counterpart in
  C or Perl, since the other XOR operator (^) works on bits.  The best
  equivalent for C<$a xor $b> is perhaps C<!$a != !$b>[1].  This operator
  can't short-circuit either, since both sides must be evaluated.

  [1] One could write C<!$a ^ !$b> or even C<$a ? !$b : !!$b>, of course.
