Take a look at the page to which Damian provided a link.  You'll find
that XOR does indeed correspond to the definition being used by Perl
6, as well as the natural language meaning.  What other languages call
XOR is actually an "odd parity check".

As I suggested above, I think that Perl 6 already addresses both of
these: use '^' or 'xor' (or 'one()') if you want XOR semantics; use
'?^' if you want "odd parity" semantics.

We never do things differently for the heck of it.
