Good afternoon Drew:
The proposal I read on the 1364 reflector has an additional sentence
fragment on escaped names within a hierarchical reference. Is it not
in the document you are reading.
The algorithm stated for resolving hierarchical references is correct.
To pharaphrase:
Examine the current scope (named block/module) for the reference.
If not found examine the parent's scope. Recurse until found or
at root.
This correctly describes what answer you should get in your example. The
answer is to consider hierarchical names as first an instance name
and second a module name. The instance name found is used.
I agree we need to say that module_instance_name can be repeated:
[module_instance_name .]+ item_name.
Maybe it should be called instance_module_name to reflect the precedence?!
