This is the behavior that we expected? or do we want to change it?
I am curious because I am having this problem in my project and I found it a little hard to debug. I didn´t expect this behavior.

Hey @carbaj0,

It's expected behavior due to how launch & Structured Concurrency 🤔 There are some things we're doing to improve debug-ability, but it won't change this specific example.

This PR also updates the docs, and improves debug-ability.

This PR by @raulraja checks this at compile time, preventing you from doing this with a compile-time check.

This is similar to the problem of:

flow {
  launch { (1..10).forEach { emit(it) } }
}
