Hey axel,
I recognize the problem space you are discussing. There are a couple
strategies I could implement to try and solve the problems. And I'm not
100% sure you can solve all of them. But I certainly don't want to jump
down the rabbit hole of reflection myself if I don't have to. So I'm
looking for a package that has attempted to do this. I'd certainly take
something that can't handle every case.
So far my googlefoo hasn't found the key words that differentiate this from
pretty printing, or this type of package doesn't exist.
Thanks for your response axel.
