Thit has led to surprising results in Pugs's Net::IRC:
if 'localhost:80' ~~ /^(.+)\:(\d+)$/ {
my $socket = connect($0, $1);
}
If $1 is a match object here, and connect() assumes Int on its second
argument, then it will connect to port 1, as the match object numifies
to 1

It looks... weird. :)
And it would have to be
if 'localhost:80' ~~

I think we already said something like that once some number of
months ago. +$1 simply has to be the numeric value of the match.
Agreed.
Anyway, while we could have
a method for the .matchcount, +$1[] should work fine too.
Yep.
Actually, it's not clear to me offhand why @1

Patrick surmised:
So I'm guessing that we're all in agreement that +$/, +$1, and
+$subrule all refer to the numeric value of the string matched,
as opposed to what's currently written about their values in the
draft...?
Yes. The semantics proposed in the draft have proved to be too orthogonal
