Pynarcissus parser post-parse analysis with a visitor like pattern

Someone recently asked me how the more time involved analyzer I wrote works, unfortunately I can’t post it as its targeted for a client project… but I can post a simpler mockup of it combined with the person’s function print logic.

Sure this loses the ability to step back up the chain of tokens, but for most cases like detecting functions or in my case line numbers to intrument, this construct works for me.
