in thread IO::Socket->recv() method documentation?

The address will be in sockaddr_in format,

Is that a scalar, an array, a hash or some kind of object?

similar to that passed to bind.

What is bind? As an IO::Socket user, I've never had to bind anything.

See the examples in Sockets: Client/Server Communication in perlipc.

There aren't any IO::Socket udp examples in perlipc.

And what code is in there seems to be written in some foreign language? Like C with dollars.

Half of the examples don't compile with strict even though someone has stuck a big my block of horribly named variables at the top.

If the modernists want something to do to make Perl look more modern, that would be a better starting place than trying to convert the world to the OOne trOO way :)

    A packed string/structure. Socket and thus IO::Socket provides tools. 

    use Socket qw( sockaddr_in inet_ntoa );
my ($port, $packed_addr) = sockaddr_in($peer);
my $addr = inet_ntoa($packed_addr);

    This answer is specific to IPv4.

    You'd know it as LocalPort.

        Yes. Are you saying you are playing the devil's advocate (trying to show that the code should behave unintuitively by taking the opposite position)? That makes no sense to me.
