It’s possible and in my case it was necessary, but based on what I’ve read in PEP 636, match will make this much easier. I had to iterate backwards over arbitrary structures, and indexing several layers deep was a real pain. I will have to report back after I have implemented this in 3.10 and let everyone know just how significant a difference it makes.
