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

Jonathan offers some nuanced opinions about packages and compilation
scopes in

   http://www.eda.org/sv-bc/hm/3282.html

Also note that if you want to share user-defined types between two
different compilation unit scopes then, according to the IEEE standard,
you need to use packages, because if you simply `include the type
declaration in those two scopes, you will be creating two different
types.  For legacy reasons (from before packages were added to SV), the
multiple-`include style probably still works with many tools, but it's
not really forward compatible with the IEEE standard.

So is the idea of compilation unit scope declarations bad?
