in reply to How To Call An Anonymous Subroutine?

You invoke an anonymous sub with ->(). Your sub would be invoked with $new_resolvers{"dns-extern"}[0]->($ip_address). The way you have your loop written, you'll have to tell the difference between a scalar and a sub though. You could rewrite the loop as:

print "getting new resolvers for dns server $dns_server\n"; for my $resolver ( @{$new_resolvers{$dns_server}} ) { if (ref $resolver) { print "$_\n" for $resolver->($ip); } else { print "$resolver\n\n"; } } print "\n";
I don't know where $ip is supposed to come from, but that's the way you have your anonymous sub written.
