Hi @isschoch thanks again for the contribution. To finish off this work, I will ask for some small changes in your code review. There is no hurry here, so feel free to get back to it when suits you.

Great work on this. I have a few small comments to make below:

Nice work again! I have a few more small suggestions.

Hey @isschoch great job on this. I am happy to see it added to the repo.

The testing seems to be failing with the recent merge from master --- I think it should be fine to try adding an empty commit to trigger the CI with: git commit -m "Trigger CI" --alow-empty and I'll reapprove the runs.

@mlxd thank you for notifying me about the runs. Sorry for pushing the change so late, is it still early enough for the 0.20-dev release?

@mlxd thank you for notifying me about the runs. Sorry for pushing the change so late, is it still early enough for the 0.20-dev release?

All good --- I'll let the runs go, and if everything passes I'll merge immediately for 0.20. Good job again!
