bind 

        # Addrinfo.bind

(from ruby core)

    bind() { |sock| ... }

creates a socket bound to self.

If a block is given, it is called with the socket and the value of the
block is returned. The socket is returned otherwise.

    Addrinfo.udp("0.0.0.0", 9981).bind {|s|
      s.local_address.connect {|s| s.send "hello", 0 }
      p s.recv(10) #=> "hello"
    }
