1) I’d still like to see "an unnamed UnixDomainSocketAddress" used instead of "UnixDomainSocketAddress with an empty path” - since we have a nice definition of _unnamed_ already.

2) I wonder if we can add the following definitions:

  “channel for an Internet protocol socket”  - channel::getProtocolFamily returns one of INET or INET6

  “channel for a Unix domain socket” - channel::getProtocolFamily returns UNIX
