Iterables, AsyncIterables, Observables, Oh My!

I know there is a lot of confusion around Observables, Iterables, AsyncIterables and AsyncObservables. Let's try to break this down and the reasons for each.

Pull versus Push Collections

When it comes to collections, you have two ways of thinking about collections, push versus pull. With pull, the consumer is in control of when you get the items, but with push, you get the values when the producer is ready.

Pull Based Collections

export type User = ReturnType<typeof verifyUser>;

// ^ Type defined for 'free'
// + Pro: Less wasted effort aligning types AND validation.
// + Pro: More 'honest', not obscured by layers, `any` or `as`
// - Con: Easy to accidentally change a public interface.
//      (Prefer explicit definitions at your library/module boundaries.)
export function verifyUser(data: { [key: string]: unknown; }) {
  if (!data || typeof data !== 'object')
    throw new Error(`User must be a valid object.`);
