The only time unconnected ports must be explicitly listed as empty
ports is when you are using .* for the port connections.  That is
because .* is a request to connect all ports.

In all other situations, unmentioned ports are unconnected, regardless
of whether you specify the connected ports with .name or .name(signal).

Stu said at today's SV-BC meeting that you and he intended it to
work differently, but neither the LRM text nor anyone else at the
meeting supported that interpretation.
