I see a couple of options: 1a: Use a default type annotation, if one is not is supplied. typing.Any would presumably make the most sense. 1b: Use None if not type is supplied. 2: Rework the code to not require annotations at all. I think I'd prefer 1a, since it's easy.

2) would be great :-) I find this bit of “typing creep” makes me nervous— Typing should Never be required! ​+1 ​

I understand that the intent here is that the user could ignore typing and have it all still work. But I’d rather is was not still there under the hood.

Just because standardized way to do something is included in core Python doesn’t mean the standard library has to use it. ​I trust my repetition of the point that the stdlib is an important learning resource isn't unduly harping on the subject. Python is in danger of becoming pretty arcane rather too rapidly for my own liking​, though I confess to being mostly a consumer of Python.

However, typing is not currently imported by dataclasses.py.

And there you have an actual reason besides my uneasiness :-) - CHB ​hmm...​ -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://mail.python.org/pipermail/python-dev/attachments/20171215/e4a7e5c7/attachment.html>
