Hi, dependency question:
so to just work with the new effect-system (basics like either-computations using suspend functions, not the scheduling and concurrent API), I need to depend on arrow-fx and not necessarily on arrow-fx-coroutines ?
(0.12-SNAPSHOT)

Hey @Jörg Winter,

If you just want access to either { } then having a dependency on Arrow Core (arrow-core) is sufficient.

Arrow Core is inline in wherever possible to allow suspension to be used inside it's lambdas. The either { } DSL is also suspend, and thus allows the use of suspend functions inside.

For a non-suspend version of either { } you should use either.eager { }.

If you want access to parMapN, parTraverse, and other concurrency APIs you want a dependency on Arrow Fx Coroutines (arrow-fx-coroutines).

Arrow Fx (arrow-fx) is a module that's being deprecated in 0.12.0 and will be removed in 0.13.0.

Hope that helps 🙂
