Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface Fn4<A,B,C,D,E>
extends Fn3<A,B,C,Fn1<D,E>>

A function taking four arguments. Defined in terms of Fn3, so similarly auto-curried.
