Raymond, I think you didn't understand the issue. Glossary already _has_ the ammendment you mention (at least for the __getitem__ - I'm not sure any of other examples you mention are counterexamples to that interpretation: callable_iterators and generators _do_ have an __iter__ attribute, and they are correctly detected as instances of collections.abc.Iterable).
I wanted to push in the _opposite_ direction, to fully bless __getitem__ as a way to declare iterability, so it could be recognized by Iterable's instancecheck. Because it seems to me that whoever wrote that instancecheck, didn't have the _intention_ to exclude __getitem__ iteration.
Or at least, if we cannot do that because of backward compatibility:-(, to explicitly document that Iterable ABC _does not_ fully encompass what we mean by "being iterable". |
