Trying out the thing, and since this is ycombinator after all: type Lazy = () => A; const lazy = (f: Lazy ) => { let thunk: Lazy = () => { throw null; } thunk = () => { const y = f(); thunk = () => y return y; }; return thunk; }; const tap = (f: Lazy ) => Lazy >, a: Lazy ): Lazy => lazy(() => f()(a)()); const ap = (f: any, a: any): any => tap (f, a); const y = (f : (a: Lazy ) => Lazy ): Lazy => ap(((x: any) => ap(ap(…
return thunk;
return () => thunk();

Though you need to replace: return thunk; with: return () => thunk(); Otherwise the assignment in thunk does nothing.
so, observablehq. i like it. what's the pricing, and can you save private docs?
