This could be a simple / cheap way to get a time-travelling debugger. Run your code through vardbg generating a video. If that run results in unexpected behaviour then you can step back and forward through the video and see where things went wrong.

Or just use rr.

vardbg is for Python, so rr isn't very helpful.

However, you could use RevPDB: https://morepypy.blogspot.com/2016/07/reverse-debugging-for-...
