Re: [sv-bc] $unit::m or $root.m in module instance?

Module names are in a global definitions name space, not in some
particular $unit.  But to bind instances to different source
descriptions, a configuration can be used.  

Should 

      topmodule_identifier ::= identifier

be

      topmodule_identifier ::= [ $root ] | identifier

?

Subject: [sv-bc] $unit::m or $root.m in module instance?

It might be useful, in the presence of nested modules, to specify a
module name in a module instantiation using $unit or $root:

    module top();
        $unit::m1 u1();
	$root.m2 u2();
    endmodule

The lrm says that the module name in a module_instantiation has to be an
identifier.  This rules out using $unit::<id> and $root.<id> as module
names.  I wonder if this restriction is intentional.
