What would you like to see?

When you are trying to review the first 2 levels of the Open ladder of functional programming using Kotlin and Arrow, I don´t find many examples in the documentation about the following topics:

• arrow.syntax.function.curried
• arrow.core.and

I expected Validated to have an ap method or something, but I can't seem to find it. The only docs I can see are https://github.com/aol/cyclops/wiki/Validator, which clearly isn't the current implementation, and I notice aol/cyclops#826 as another issue, but I don't see the proposed ap method.

I opened this issue to discuss how can we improve the docs.

It's very valuable the input from users, as I have a deep knowledge of the library already, so my view doesn't help a lot.

We can start compiling a list of things we need to add, like another tutorial, some how-to sections, a better readme or doc home page and so on.

Something like this

class Resource<A> {
  IO<A> acquire;
  Consumer1<A> release;

  Resource(IO<A> acquire, Consumer1<A> release) {
    this.acquire = acquire;
    this.release = release;
  }

  public <B> IO<B> use(Function1<A, IO<B>> use) {
    return IO.bracket(acquire, use, release);
  }
}
