Robin Combinator

Rotates three arguments cyclically. Useful for reordering arguments in a circular pattern.

export const Robin = (x: Fn) => (y: Fn) => (z: Fn) => y(z)(x);
export const R = Robin;
export const Rotate = R;

const apply = (x: number) => (f: Fn) => f(x);
const double = (x: number) => x * 2;
const rotated = Robin(double)(apply)(5); // 10
