Yeah it’s not technically DAG since it uses iteration, but then dgsh will use iteration under the hood too.

However Murex does support CSP-style concurrency. So while there’s no syntax sugar for writing graphs, you can very easily create adhoc pipes and pass them around instead of using stdout / stderr.

So it wouldn’t actually take much to refine that with some DAG-friendly syntax.

In fact maybe that can be my next project…
