Besides making this possible (and guaranteeing I won't get into namespace entanglements with superclass members), I really like the idea of genuine encapsulation in perl. Etc. "Inside out". That is freaking brilliant. Somebody deserves a prize for that one.

On behalf of the many people who have worked on refining the idea of inside-out classes, we're extremely glad you're so pleased. And, yes, we actually did get a prize: the ability to do clean encapsulated OO in Perl. ;-)

BTW, if you like the idea of inside-out objects, you're going to love the framework we've build to make them easier to use: Object::InsideOut. Using that framework, your above solution could be written like this:

{ package test; use Object::InsideOut; use IO::Socket::INET; my @socket :Field Handles(IO::Socket::INET) :Default( _make_socket() ); my @field :Field Arg(field) Get(getField); sub _make_socket :Private { return IO::Socket::INET->new( PeerAddr => '', Proto => 'tcp', Blocking => 0 ); } sub _cleanup :Destroy { my $self = shift; print STDERR "Bye from $field[$$self]!\n"; } } my $obj = test->new(field => "okay"); print $obj->getField."\n"; print $obj->sockhost."\n"; my $two = test->new(field => "two"); print $two->getField."\n";

I would encourage you to take a look at the module. It may quite literally turn your world inside-out.
