RE: [sv-bc] A question regarding the proposal for issue # 91

 I agree. The general rule should be that a packed or unpacked range should not be allowed unless there is an identifier that it can relate to. So that should restrict them to declarations (or prototypes)

I assume the same reasoning applies to parameterized types. If you
have:

    sub #(.t(reg[10:0])) u1();

then it's equally unclear whether you are parameterizing type t of module sub with a packed or unpacked array of bits.
