      A version of dir that returns all the members that can be seen by getattr_static.

      Would it respect __dir__?

      No. It would return all members accessible to getattr_static (which is completely unrelated to what __dir__ may or may not return). Also calling __dir__ would mean code execution, and the point of these functions is to avoid this where possible.

      A first patch, misses any documentation changes. While working on it, I realised that modules technically shadow the dict attribute (because modules use tp_dictoffset, hence module have a dict member that points to the instance dict). I updated _shadowed_dict() so that it now disregards member descriptors as shadowing (as they will never trigger any code execution), but theoretically, the members can be any object (not just dicts), so I have to think a bit more about that case (as a custom object still can trigger code execution).

      Also, dir_static() behaves slightly different from dir() (e.g. dir() raises a TypeError if the module's "dict" attribute isn't a dictionary, which is kind of impossible for dir_static as it doesn't even try to acccess __dict__ if it is shadowed), but IMHO such edge-cases are expected to behave differently for a static version and hence we don't care at all about that.

      Thanks for the patch Andreas. On a quick read through it looks good. I'll do a proper review shortly.

      See issue bpo-11813 for the module problem.
