Hm. I'd rather see:
schwartzian({/num:(\d+)/}, {^_<=>^_}, @t), and have perl figure out how to
do the forward and backword mappings. Hmm, I don't see why you couldn't
write that right now. (Other then synthatical shugar -- currying and
getting rid of the need for "sub {}"s.)
Indeed,
map $_->[0], sort {&$sort($a->[1], $b->[1])} map [$_, &$attrib($_)], @list;
does what I intendeded. (Where ex $sort = sub {$_[0] cmp $_[1]}, and
$attrib = sub {lc $_}.) (Of course, this doesn't always use the optimal
form.)
