What is required for multifile support?

[JoBoDo]

Hi @calio

I really want to use luaflow, I can see it being immeasurably helpful for my current lua project which is >100,000 lines in total... there are a few key sections which I want to drill down and optimize but they are split across a few files. It's on your todo but 4years without an update... I'm guessing you're no longer planning to multifile support. Could you please give me some tips to go in the right direction in order to add multifile support?
