I think there is some hope of a sane wrapper around C++20 coroutines that will make them easier to use. I saw a tutorial a while back mentioning that might eventually become part of the C++ standard. I once tried to use Boost coroutines but it was too much headache and I switched to a different approach.

Erlang's processes and Goroutines are stackful unlike C++ coroutines. Erlang also forbids observable data sharing between processes which avoids a lot of pitfalls. I don't think that can be enforced in C++ or Go.

GHC lightweight threads and its STM library (software transactional memory) could be another thing to look at. I wonder if a useful STM feature is feasible for tiny_coro.

You are spot on about the distinction. C++ chose the stackless path for "zero-overhead" efficiency, but it definitely shifts the burden of safety and usability onto the library developers. Regarding safety and data sharing: You're right, C++ won't enforce isolation like Erlang. That's the trade-off we make for performance. However, to address your point about "sane wrappers" and concurrency models: I actually implemented Go-style Channels (CSP) on top of this scheduler to bridge that gap. It uses co_await to mimic Go's channel behavior, supporting Direct Handoff (skipping the buffer/queue if a receiver is waiting) and optimization via await_suspend returning false to avoid context switches on the fast path. While a full-blown STM might be too heavy, I found that combining these Channels with Epoch-Based Reclamation (EBR) gives a pretty robust safety net without the overhead of heavy locking. If you're interested, the Channel implementation is here: https://github.com/lixiasky-back/tiny_coro-build_your_own_MN...
