I'm not certain either. The counter argument is that Socket is called
Socket, not Socket4, and (I think) is intended to provide general
functionality, not just IPv4.

Plus, I think (and I'm assuming a rough consensus here, until proven
otherwise) the perl core should be shipping complete IPv6 functionality
(well, as complete as it currently ships IPv4).

I right in guessing that without this constant exposed *somewhere* by a
module shipping in the perl core, we'd not meet that goal?
