For those of you that have seen and reviewed @simon.vergauwen work in the suspend library over the last 4 weeks introducing suspend without IO and the same power please show your approval or comments here today. This is going in today to get a snapshot ready for Kotliners. https://github.com/arrow-kt/arrow-fx/pull/169

[PhBastiani]

More concise, ...., More idiomatic 👌

[PhBastiani]

Is there use cases where we cannot use the new suspend DSL ?

[simon.vergauwen]

No, you can use it everywhere and it exposes no unsafe APIs

[simon.vergauwen]

Similar to what you’d expect from IO expect for the wrapping

[raulraja]

Essentially eliminates the need for IO and transformers like EitherT

[PhBastiani]

Due to a professional meeting, I could not attend Kotliners. Hopefully the videos will be online soon...
So, I ask a question here: if i've this API

MyClass<F> : Async<F> {
fun <A> myfun(use: suspend MonadThrowSyntax<F>.(MyDataClass) -> A): Kind<F, A> = fx. ...
}

If I understood correctly, with the new DSL, I can write

MyClass {}
suspend fun <A> MyClass.myfun(use: suspend (MyDataClass) -> A): A = ...
or
suspend fun <A> MyClass.myfun(use: suspend (MyDataClass) -> A): Either<MyError, A> = ...
}

Exact ?

[simon.vergauwen]

Yes, that’s 100% correct

[simon.vergauwen]

Have you checked the README in the PR? It covers most of these topics there

[simon.vergauwen]

Otherwise feel free to ask more questions here, the idea is that that README will become the Quick start section for the library. So all information you think is missing I’d love to know, so I can write it down for future reference when working on the docs 😉
