Hm, but wouldn't whose be equivalent?
sub foo ($bar) {
$bar.say;
}
multi sub foo ($bar) {
$bar.say;
}
Aren't subs a subset of multi subs, meaning that every sub can be
expressed as a multi sub?
Is there anything a sub has in advantage of a multi sub?
So might not just every sub be a multi sub?
If the only difference is, that you _must not_ declare a sub twice with
different argument lists, I think that this one is relatively
unimportant and letting every sub be a multi sub seems to be more
consistent to me in opposite to this arbitrary looking distinction.
Maybe I just phenomenally misunderstood multi subs, but unless I did, I
can't see why we want to have subs when we can have multi subs that can
do the same and even more.
