2607. Visibility of enumerator names

Section: 10.2  [module.interface]     Status: drafting     Submitter: Richard Smith     Date: 2022-06-28

Consider:

  // module interface unit
  export module M;
  export enum E : int;
  enum E : int { e };

  // other translation unit
  import M;
  auto a = E::e;  // #1: OK?
  auto b = e;     // #2: OK?

It is unclear whether the enumerator name e is or ought to be visible in the other translation unit.
