:  to denote the class NAA nested in the base class AA of AA1.

Since people seem to diagree what the "natural" rule is for
scope order when both nesting and inheritance are considered, I'd
rather keep AA1::AA::NAA for both cases, and require that these
expressions be unambigous.

Even if clear rules are defined, I think it will be confusing
if the same name may appear along different inheritance/nested
paths.  It is (kind of) the visibility aspect of multiple inheritance
applied to nesting as well.
