Thanks for the contribution, all the changes seem reasonable to me.

Regarding your reply on Twitter, I'm not sure if you have any plan to proceed on "deeper" review. I'll keep this open for a while, so feel free to push additional changes (if you have any). When the review is complete, please notify us so that we can merge this.

BTW: Our CI is failing for some technical issues. We will fix this on our part.

I rebased your branch on HEAD and force-pushed into your fork. We have updated our configuration to allow workflow runs from outside contributors, so I think the error is fixed now.

Please run git fetch origin && git reset --hard origin/pr/fix on your local machine. (Make sure to backup your local work before doing rebase.)

Note that the semantics on recursive_wrapper has changed in #45. Sorry for the inconvenience, but the change is minimal, and actually simplifies the semantics, so tracking the change should be easy. No other parts are affected, as of now.
