Interest in including OrderedSet in python standard library?

[jagerber48]

Hello, I am interested to know if the maintainers of this package would have interest in including this functionality in the python standard library. It seems natural for OrderedSet to sit next to OrderedDict in the collections package. There is a discussion on the Python Discussion Forums. It is not clear-cut that it should be added but I wanted to gauge the interest of the folks maintaining the current Python ordered set implementations.

Hi!

1. A Cython package wouldn't ever get added to the stdlib;
2. there are several issues open for this package relating to edge cases in comparisons (to other sets, to other collections);
3. this library was written before the dict implementation in python was insertion ordered

I do think it would be good to have an orderedset in the stdlib, but this library is probably not a good fit for it, and I'd rather have a new C implementation based on the implementation of dict.

I see, that information and feedback is very helpful, thank you!

4. This library doesn't even work anymore. It doesn't install.
