honestly the hard part of go concurrency was never starting goroutines, it's making cancellation and shutdown behave. nice to see context, races and diagnostics in one runnable place.
Yup. That’s because cancellation isn’t native, but part of the context object and requires cooperation. In a language where goroutine switching is preemptive rather than cooperative, I find it odd to have cooperative cancellation, until I realize that Go doesn’t have exceptions and probably will never have them.
exactly - once you accept go has no exceptions, context cancellation is basically the least bad way to tell a goroutine to stop.
