Actually, I don't think this is a bug, 'module Foo' in the export list
is defined to export all names in scope which are of both in scope under
the names 'Foo.bar' and 'bar' and both names refer to the same entity.
There is no particular reason this set can't be empty.
though, it certainly could be warning-worthy.
