 * Note that since the promise is completed with a task, the effect will
 * be evaluated each time the value of the promise is retrieved through
 * combinators such as `wait`, potentially producing different results if
 * the effect produces different results on subsequent evaluations. In this
 * case te meaning of the "exactly once" guarantee of `Promise` is that the
 * promise can be completed with exactly one effect. For a version that
 * completes the promise with the result of a task see
 * `Promise.complete`.
