@TomHall2020 I think this is ready to be merged if you fancy casting an eye?
It updates a number of the 3.10 things that came up during your recent PRs.

Yeah looks good, there's the option to clean up some of the type hinting syntax but that isn't necessary and depends a bit on taste anyway, plus theres always more stuff coming in future versions.
