Would be interesting to hear what levels you think those are because as someone who has been learning and writing C++ and Python for over 20 years now, I'd say there's no level of Python which comes even close to the complexity of C++ at a comparative level.

> getting something from e.g. Python 1.6 to run on 3.12 is an exercise in trial and error, or unexpected surprises at some moment at runtime.

Fair enough. But then again: that's irrelevant for any new project written since about the start of the last decade. And to continue the C++ comparison: whereas Python 1 -> 2 -> 3 imo solved some real issues, the consecutive C++ standards never did this resulting in something which is, yes, backwards comptible (roughly - try getting 30-40 year old code getting to compile with /std:c++latest and /Wall - or look at all those tiny behavior changes between the last couple of standard iterations) but also seriously plagued by that as it holds back innovation. Modern C++ minus a lot of the old UB-prone stuff would definitely be better and less complex than what we have now.

If you give the tiniest of Fs for your user, do not write your thing in python.
