Goldfinch Combinator

Composes functions with swapped middle arguments. Useful for complex function composition with argument reordering.

export const Goldfinch = (x: Fn) => (y: Fn) => (z: Fn) => (w: Fn) => x(w)(y(z));
export const G = Goldfinch;

const multiply = (x: number) => (y: number) => x * y;
const addOne = (x: number) => x + 1;
const complex = Goldfinch(multiply)(addOne);
const result = complex(3)(10); // 40
