[sv-bc] Mantis 2929: ref_declaration should use list_of_variable_port_identifiers

Mantis 2929 requests to allow non-ANSI ref ports to be variable-size arrays.

In detail, the non-ANSI port declaration syntax currently looks like this:

inout_declaration ::= inout net_port_type list_of_port_identifiers

input_declaration ::=
  input net_port_type list_of_port_identifiers
| input variable_port_type list_of_variable_identifiers

output_declaration ::=
  output net_port_type list_of_port_identifiers
| output variable_port_type list_of_variable_port_identifiers

ref_declaration ::= ref variable_port_type list_of_port_identifiers

The difference between list_of_port_identifiers on the one hand, and list_of_variable_identifiers and list_of_variable_port_identifiers on the other, is that the former allows only fixed unpacked dimensions, whereas the latter two allow variable-sized unpacked dimensions.

So input and output port declarations already allow variable-sized dimensions.

(The difference between list_of_variable_identifiers and list_of_variable_port_identifiers is that the latter also allows an initializer.)

ANSI-style ref declarations also seem to allow ref ports to have variable-size dimensions.

Are there any objections to changing the ref_declaration syntax to use list_of_variable_identifiers (not list_of_variable_port_identifiers)?

Thanks,
Shalom
