Why wouldn't I skip this and go straight to:

• Port wrapt to heap types and stable ABI #187

This PR is pretty much safe, does not introduce any nasty C bugs, and removes all Python 2 related quirks.

PR #187 doesn't remove all Python 2 code. There is also a possibility that it introduces C bugs or ref leaks. It needs a thorough review.

Given that you drop support for Python 2.7 explicitly, I guess it's perfectly valid to release it as 1.14.0 (contrary to what I originally wrote in #189 (comment)). I realized that pip will not install 1.14.0 in a Python 2.7 environment if the support is dropped explicitly.

Thanks a lot for this change ❤ - I fully support it (but you do not have to listen to a n00b like me 😉)

Such PR essentially removing this amount of compatibility boilerplate and still passing the test suite for python 3.6-3.10 and pypy can only be approved! Looks Very Good To Me.

I also vouch to integrate this separately from #187 for the sake of the VCS sanity.

Taking a look at this, and testing against Python 3.11a6, wrapt fails to install on Python 3.11 due to setuptools.formatargspec being removed. However, since this PR drops support for Python 3.5 and lower, it should be replaced with setuptools.signature as recommended in the release notes for Python 3.11

Version 1.14.0 of wrapt deals with Python 3.11 changes. This PR would need to be rebased against that.

I believe everything covered by this has been integrated now. I did it manually but cross referenced everything here to make sure got everything. Sorry for the delay, but life has been a challenge since covid. 😩
