Does nim have a concurrency story yet? That’s what gave me pause last time I checked it out.

Yep. Concurrency is achieved via async await. Parallelism via `spawn`.

Where is supporting use of multiple cores on the roadmap?

Compile with `--threads:on` and everything in the threadpool module are available. You can also use `CreateThread` for long-lived threads.

Alternatively, you have an open-mp for loop that you can use with `||`:

    for i in 0||1000:
      doParallelSomething()
