On a related note, it seems parMapN and parTupledN supports only arity 3, but I need to invoke it with 4 arguments. 😞
Should this be extended to at least arity 5?

Hey @Attila Domokos,

Good point!
Yes we should actually support up to 9 arity, like we did in Arrow Fx.
This is not there yet since I started development on this library with only a dependency on the Kotlin Std to I didn't have TupleN available.

[Attila Domokos]

I have not checked, does arrow.fx.coroutines have now dependency on arrow.core?

[Attila Domokos]

To start using TupleN .

[simon.vergauwen]

Yes, it does 🙂 Finding the correct encoding for implementing IO as suspend was actually very tricky, or at least it took my quite a while to figure it out 😅

[Attila Domokos]

I'll take a look at it, thanks Simon!

[simon.vergauwen]

Awesome, thanks Attila!

[Attila Domokos]

Had to use 2 parMapN for 4 parallel calls, and destructure pairs of pairs. Too complex for a simple use case.

[simon.vergauwen]

Yes, 100% agreed!! That's also why I made this PR, so you don't have to destructure anymore and can also simply pass method references.
