Another thing that can prove interesting and is worth investigating is how `zig`
is managing async stuff right now (the new `IO` struct).

I don't have an example at hand nor I know completely how it works, but
basically they managed to resolve async without 'coloring' the language and
without making it system-dependent. That's again _super_ desirable, specially
for OSDev where you don't have threads from the start, you'd use `IO` to
implement your own async system.

Same as with memory management, `nim` is more opinionated on async/await, you'd
still have to implement your own.
