Major Changes

• f62b683: Simplify Do, remove promise support.

  Do no longer needs the unwrapper function.

  // before
  const x = Do(function*($) {
    const a = yield* $(Result.Ok(1))
    const b = yield* $(Option.Some(2))
    return a + b;
  });
  
  // after
  const x = Do(function*() {
    const a = yield* Result.Ok(1);
    const b = yield* Option.Some(2);
    return a + b;
  });
  

  A side effect of this is that unwrapping promises is no longer supported. This is a breaking change, but it is for the better.

  Promises are not a good fit for the Do notation, and it is better to use async/await instead. Promises also have no way of tracking the Error type, which is a big limitation.
