I think Perl 6 should have a but keyword, as in:
if (defined $foo but $foo eq ) {
}

It can't be that confusing at first glance if English dedicates a slot
way up in the huffman table to the word, eh?
print ;
if ($need_eol but $current_column 21);
OTOH, this might become an and grep-not operator for (was it
Damian?)'s quantum operators:
@y = all(@x) but { /^anti/ };

An off-the-wall thought... If this is not the expected condition,
should it have the extra meaning of an assertion? For example,
could set $! to 'defined $foo but $foo eq ' and, if -w was in use,
issue 'warn Exceptional condition: $!'
Interesting idea;

Of course you will now be able to say:
if ($foo // ne bar) { }
Right?
