RE: [sv-bc] Proposal to make it easier to use packages with port declarations

Brad,

I do not have a strong preference for either of the proposed syntax styles,
though I do have a slight preference to using the already existing V2K
parameter list just because it looks more like Verilog.  The important thing
to me is the ability to use package definitions in port declarations without
having to redundantly name the package for each port.  I will leave the
fine-grain details on where semicolons and such are needed to parser
experts.
