I created the module and moved Option there.

At first I made arrow-option depend on arrow-core-data (Option need Show, Predicate, Either and a few other utilities from core-data).

However arrow-core-data also needs Option. MonadLogic, Monoidal, Semigroup, Travers etc... use it internally or in a public API.

Since Option was marked for deprecation, I assume removing the Option usages from arrow-core-data is the way to go, right?

Semigroup uses Option internally, this can be replaced with nullable types without altering the public API

[stojan]

FunctorFilter uses Option as part of the public API....

fun <A, B> Kind<F, A>.filterMap(f: (A) -> Option<B>): Kind<F, B>

do I also replace this with nullable types? (that would change the public API without deprecation cycle)

Makes sense, yeap that should be good, thanks Stojan!

For FunctorFilter I think it's fine since it has been released deprecated already without an alternative 😞

Also we may want to consider rename to mapNotNull.
