Hello @Julian

The CI is marked as red due to coverage, but you could be interested ?

[Julian]

@Djailla hi! Yes, thanks for sending it.

This likely is something I'll want to do in the next few months, but there's likely a few things higher on the list for limited time :/ -- the one thing I see is we need to set a python_requires in the setup.cfg as part of this change, so that we don't break Python 2 for any existing versions.

But beyond that yes would be interested, just may take me a bit to get to this.

Thanks for sending it!

[Julian]

Merged, thanks!

Awesome! This solves a lot of the headaches I was having with #708 (PR #712)!
