abstract class Visitor[F[_], A, R] extends (Iterant[F, A]) => R

Implements the Visitor Pattern for interpreting the Iterant data structure.

This can be used as an alternative to pattern matching and is used in the implementation of Iterant for performance reasons.

WARN: this being a class instead of a recursive function, it means that it often has to keep "shared state". Keeping shared state is great for performance, but breaks referential transparency, so use with care.
