[PATCH] D31235: Enhance -Wshadow to warn when shadowing typedefs or type aliases

[Eric Fiselier via Phabricator via cfe-commits]

EricWF added a comment.

This started making the libc++ bots fail, and I'm not convinced the case is reasonable to warn on. That case is:

  struct path {
    using value_type = char;
    struct iterator { 
      using value_type = path;
    };
  };

Obviously both typedefs are necessary, and according to the standard they are both required to have the same name. I would prefer not to have to `#pragma` disable this diagnostic within `<filesystem>`
