I have the following code that I believe should function as an echo server.

#!/usr/bin/env perl
use strict ; use warnings ;
use AnyEvent ; use AnyEvent::Handle ; use AnyEvent::Socket ;

my $main = AnyEvent->condvar();

tcp_server undef, undef, sub {
    my ($fh, $host, $port) = @_;

    my $handle; $handle = AnyEvent::Handle->new(
        fh    => $fh,
        on_error => sub {
            my ($hdl, $fatal, $msg) = @_;
            AE::log error => $msg;
            $hdl->destroy();
        },
        on_eof => sub {
            my ($hdl) = @_;
            $hdl->destroy();
        },
        on_read => sub {
            my ($hdl) = @_;

            $hdl->push_read(line => sub {
                my ($hdl, $line) = @_;
                if ($line =~ m/quit/i) {
                    $hdl->push_write("goodbye\n");
                    $hdl->destroy();
                }
                $hdl->push_write($line);
            });
        }
    );
    $handle->push_write("Hello $host:$port\n");
}, sub {
    my ($fh, $thishost, $thisport) = @_;
    print STDERR "$thishost:$thisport\n";
};

$main->recv();

However, when I netcat into the server. I see the greeting and the server immediately closes the connection. I'm probably missing something simple, but not sure what. Thanks!
