Functional Error Handling
Exceptions in OOP centric langs such as Java are abused for control flow and event signaling. Lack of proper support for Monads, Higher Kinded Types and other facilities leave lang users with no alternative but to choose happy paths as return types of method signatures.
In this talk we will cover some examples regarding the misuse of exceptions and proper data types such as Option, Try, Either[E, A] and MonadError[M[_], E] to model absence of values, failing computations and alternate paths in method return types.
