How can I support cancellation within a `suspend` function? If I don't use `launch/async` etc to launch anything

<https://kotlinlang.org/docs/reference/coroutines/cancellation-and-timeouts.html>

You either use cancellable suspending functions (yield, delay, etc) or check for isActive

Right, but if I'm just in a `suspend` function without any context, how should I do that? Maybe I misunderstand suspend functions but:
```
suspend fun sample() {
   // no isActive
}
```
I could launch something but I don't want to potentially change scopes/dispatchers

Wow, I had no idea such a variable existed. Thank you!
