Never really thought about this but it seems to me that if you want to launch separate processes? Goroutines are built around functions, so you're just stuck with function semantics. If you want an entire process, you just invoke self with a feature flag on your binary and control a subprocess. If you need to communicate you establish your own message passing channels with STDIO or something.

I don't feel this is hacky or even a work around. Just different promises on what goroutines are vs threads/concurrency/processes in other languages.

Exit and panics are promised at the process level in Go.
