I'm trying how far I can get mimicking Lua's asymmetric coroutines in Nim, using iterators and some macros - not unlike asyncmacro.
The manual is a bit vague about iterator arguments - it states that you need to provide the arguments to each call, or wrap the thing in a closure which does that for you. But I want to leverage the fact that I can pass _different_ arguments to each call - is that considered safe and well defined behaviour? It works for me now, but is this intented an something one can rely on to be like this in the future?
