Subject: Enforce scalar return on ->peerhost/->peerport
At the moment, peerhost and peerport can return empty lists. Being able to rely on them always returning a single scalar (i.e. undef rather than () if there's no current value) would simplify some calling code. From a casual glance at the current implementation, it would be quite easy to assume that scalar context is already enforced: sub peerhost { my $self = shift; ( $self->_get_host_service( $self->peername, NI_NUMERICHOST, NIx_NOSERV ) )[0] } sub peerport { my $self = shift; ( $self->_get_host_service( $self->peername, NI_NUMERICSERV, NIx_NOHOST ) )[1] } which of course isn't the case, since _get_host_service could be returning an empty list. At the moment, you can't use them in a hash or as fixed-position sub parameters: my %details = ( host => $sock->peerhost, port => $sock->peerport, ... ); => could end up as { host => 'port' } cheers, Tom
