Async IO seems to be a bit racy
my $server = IO::Socket::Async.listen('localhost', 5000).tap(-> $conn {
my $message = '';
$conn.chars_supply.tap(-> $chars {
$message ~= $chars;
if $message.index("\n") -> $end {
$conn.send($message.substr(0, $end) ~ ' back').then({ $conn.close });
}
}, quit => { say $_; });

Inserting this into Actions.nqp stops the serialization of NQPMatch objects. For why?
