Applicative functors and monads have conquered the world of functional programming by providing generaland powerful ways of describing effectful computations using pure functions. Applicative functors provide away to compose independent effects that cannot depend on values produced by earlier computations, and allof which are declared statically. Monads extend the applicative interface by making it possible to composedependent effects, where the value computed by one effect determines all subsequent effects, dynamically.This paper introduces an intermediate abstraction called selective applicative functors that requires alleffects to be declared statically, but provides a way to select which of the effects to execute dynamically. Wedemonstrate applications of the new abstraction on several examples, including two industrial case studies.
