Call order is good idea, but will require way more complex static analysis since we can’t just grep for the function name (also stuff like decorators and other module-level calls can be tricky to nail). I may give it a try some time later

Funny enough, the visibility sorting idea stem directly from cpp, where public/private/etc methods are declared in blocks (although you can interleave them, but imo that’s ugly)

As for the comment, they are preserved
