refactoring identifier separator

[dalance]

Now :: and . are used as identifier separator.

import PackageA::A;

module ModuleA (
    a: input PackageA::struct_t,
    b: modport InterfaceA.master,
) {
    assign a.memberA = b.funcA(1);
    assign b.portA = PackageA::parameterA;
}

Almost . is used for [instance/variable identifier].[member identifier] and :: is used for [type/definition identifier]::[member identifier].
But InterfaceA.master seems to be inconsistent.

How about InterfaceA::master? and is there another case?

import PackageA::A;

module ModuleA (
    a: input PackageA::struct_t,
    b: modport InterfaceA::master,
) {
    assign a.memberA = b.funcA(1);
    assign b.portA = PackageA::parameterA;
}
