The thing is, we tried coroutines in C (embedded) y-e-a-r-s ago. It was all the rave for a bit. There were a couple different macro/libraries you could use with duff's device and other trickery to get coroutine-ish things in C.

Maybe the implementation just wasn't up to where it needs to be with these newer/slicker/more integrated versions, but mine (and others') issues with them wasn't the weakness/caveats of the implementation, but rather with the mess of spaghetti it made as your coroutine use grew with any degree. In onesie twosies under nice demo cases (look ma, I get some data from the intertubes with this syncy thing), they're great, but my experience was that they're a mess when scaled.

I'm happy to be proven wrong. I get to use them a bunch in Kotlin, I'm trying not to be a victim of my experience. I'm still on the fence.

Those libraries were always somewhat of a hack. Async Rust is an official language-backed syntax.
