Arity POC
IMO the only thing stopping this for now is the inability for Nextflow to handle arity in optional inputs/outputs. I made an issue about this: https://github.com/nextflow-io/nextflow/issues/5111
Do you want arity on every input?
Or just in use cases like these or even better where we expect 2 files?

I would prefer it on each input (this also has some self documenting purposes), but I'd wait until Nextflow supports arity for optional paths
On the one hand, I like self documentation, but I think we shouldn't let this hold us back from at least adding arity: in the cases where paths are mandatory.
Is this one of those module overhaul tasks?
Not yet but I think it should be :)
@nvnieuwk Do we leave this open until the issue is fixed on the Nextflow side?
Yes please leave this open a bit longer, I'll try and chase this when I find some more time in the coming weeks/months
