This is a big advantage of Nim (https://nim-lang.org/), which on the face of it is a pretty similar kind of language with a more Python-like syntax. Nim supports real threads with message passing channels (similar to Go).
Could you specify what are the differences from Go, in this regard are, please?
Nim also supports lighter-weight parallelism with the `spawn` (unsafe, unstructured parallelism which schedules a procedure to run in a thread pool) and `parallel` (lets you use a subset of the Nim language to create concurrency safe tasks) keywords which pass tasks to thread pools in the background. You can read more about Nim's concurrency here: https://nim-lang.org/docs/manual.html#parallel-spawn-spawn-s...
Go has Goroutines which use less resources than threads on most operating systems while also taking advantage of multicore CPUs (I assume they must run in a thread pool running in the background?). It also supports a select case statement which is a nice bit of syntax sugar for managing multiple channels, which Nim doesn't support (although its macro system is pretty powerful, so you could plausibly come up with an equivalent). Go does not support shared memory communication as a language feature, although some libraries apparently give you that option.
