You can sort of already do that:

sub subname { a$ cmp $b};
$r = 'subname';
sort $r @array;

or:

$r = sub { $a cmp $b };
sort {&$r} @array;

Although it would be handy in certain circumstances, and probably faster,
to be able to say:

$r = sub {...};
sort $r @array;
grep $r @array;
map $r @array;

(and $r = 'subname'; grep $r @array; map $r @array;)
