Proposed resolution (approved by CWG 2024-03-01)

Change in 6.5.4 [basic.lookup.argdep] bullet 3.2 as follows:

  • ...
  • If T is a class type (including unions), its associated entities are: the class itself; the class of which it is a member, if any; and, if it is a complete type, its direct and indirect base classes. ...
  • ...

[Accepted as a DR at the March, 2024 meeting.]

Subclause 6.5.4 [basic.lookup.argdep] bullet 3.2 specifies:

  • ...
  • If T is a class type (including unions), its associated entities are: the class itself; the class of which it is a member, if any; and its direct and indirect base classes. ...
  • ...

It is unclear what happens if T is incomplete, for example because it was instantiated from a template whose definition was not (yet) available.
