And it would have to be
if 'localhost:80' ~~ /^(.+)\:(\d+)$/ {
my $socket = connect(~$0, ~$1);
}
because +$1 still evaluates to 1. (The ~ in front of $0 is
probably optional.)
My suggestion is that a match object in numeric context is the
same as evaluating its string value in a numeric context. If
we need a way to find out the number of match repetitions (what
the numeric context was intended to provide), it might be better
done with an explicit C<.matchcount> method or something like that.
