Allowing multiple "scope-name"s is a lot of flexibility and power, but not sure it's useful/worthwhile.<br class="">
<br class="">
For the current discussion, I would think "scope-name" should be limited to an enclosing scope only. So you can say "private(Outer)" from an Inner class or "private(#file)" from within a class, but not "private(ClassA)" from within ClassB.<br class="">
<br class="">
(This would also solve the ambiguity of how to reference the main ClassA or a specific extension to ClassA... "private(ClassA)" can only refer to whichever scope of ClassA you are currently in.)<br class="">

But, this is getting into type-based access which is beyond the scope of SE-0025 right?<br class="">
