Comment:
The problem is that constructors/methods exported as children of a type or
class are not currently considered used.
Attached is a patch that fixes that in the case of unqualified exported
entities. For qualified entities, the subordinate names can shadow other
reader names (as the test case `T7145b` shows), so we don't add it.
Since the import has to be qualified, anyway, in that case, this should
not matter.
