Subroutines defined at compile time have package scope so it makes little sense to define them inside a loop.    You will never get a new subroutine for each loop iteration. 



        while (<$sock>) {
            $sock_string = $_;
            last;
        }

Why not just: 

        $sock_string = <$sock>;
