[ID 20000222.016] perl needs logical xor

This is a bug report for perl from chaos@crystal.palace.net,
generated with the help of perlbug 1.19 running under perl 5.00503.


-----------------------------------------------------------------
[Please enter your report here]

'foo' ^ '' gives a true value ('foo', to be precise).  Because the
bitwise operators are overloaded with magical behavior for strings,
Perl needs a logical XOR operator, ^^, so cases like this can be made
to work without rigamarole.
