Hopefully there will be some replacement. I can't count the number of
times I've relied on things like:
$b = qr/\d{1,3}/;
if (@ip = ($addr =~ /($b)\.($b)\.($b)\.($b)/)) {
die "$0: \"$addr\": bad IP\n" if grep {$_>255} @ip;
print("0x",(map {sprintf "%02x", $_} @ip),"\n");
} else {
die "$0: \"$addr\" is not an IP address\n";
}
It would be a shame to loose that.
