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 (indicating a successful match).
I "fixed" this for 6.2.3 by flattening $0, $1, $2 into plain scalars
(for nonquantified matches), and use $/[0] etc to store match objects,
but I'm not sure this treatment is right.
Is it really intended that we get into habit of writing this?
if 'localhost:80' ~~ /^(.+)\:(\d+)$/ {
my $socket = connect(~$0, +$1);
}
It looks... weird. :)
Thanks,
