It's available https://crystal-lang.org/reference/guides/concurrency.html. Fibers (like goroutines) are scheduled by Crystal and map to system threads.

The work on parallelism is available as a compile-time flag, but not yet GA: https://crystal-lang.org/2019/09/06/parallelism-in-crystal.h...

One wonders, once it is GA, if there is value in a Go transpiler. There is a lot of useful software in Go land that would be immediately useful for Crystal devs, and Go itself is not too complicated to map to another language with the same features (a few of the runtime features will have to be emulated).

How would this be achieved? Could you expand a little on this idea?

Literally convert Go code to Crystal code. I have not looked into Crystal enough to confirm it's features are a superset of Go's. For example, I saw that Kotlin w/ the advent of their coroutines, had most of Go's features so I wrote a transpiler[0] that got pretty far (can run all of this [0]). I abandoned the project because I have abandoned the JVM.
