I looked for it before but as I have upwards of 15k posts on here so finding a specific one can be difficult. Second dive picking up where I left off found this post: TypeError: getset_descriptor is not callable - #7 by jacob.small
For what it’s worth when I have seen people try to implement this they give up as it doesn’t scale beyond the simplest of use cases and things WILL break as you iterate in ways which change geometry, and when they inevitably do you get stuck with warnings to dismiss or otherwise handle.
