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

By my reading, it really is an error, not valid code. The infix:<,> is
looser than the ternary, as you say, so without parens, it parses as:
(1 ?? 1),(2 !! 3),4
I agree, however, that this shouldn't die.
I've added a test for this in t/spec/S03-operators/ternary.t
Thanks.

The correct place for this is in an email to rakudo...@perl.org, which
will lodge a ticket with the rakudo bug tracker. I've submitted this
one for you, but feel free to do it yourself in the future.
Good luck with Rakudo, and enjoy Perl 6!
