New submission from Nick Coghlan : (Alternate proposal inspired by the discussions in #35806 and #35791) Currently, a sys.modules entry with no __spec__ attribute will prevent importlib.util.find_spec() from locating the module, requiring the following workaround: def

Guido van Rossum added the comment: Option 2 sounds best. I am also not against adding __spec__ but I think we should support the idiom regardless, and I don’t consider this a bug in the typing module — at best there’s a slight improvement. On Sun, Jan 27, 2019 at 6:50 AM Nick Coghlan wrote:
