The pure purposeful programming language Haskell implements them employing monads, derived from group principle. Monads offer you a way to summary certain different types of computational styles, together with (but not limited to) modeling of computations with mutable condition (and other side effects including I/O) within an critical fashion without having getting rid of purity.
