/**
  * Creates a suspendable function. Suspendable functions may use the await() function
  * internally to suspend execution at arbitrary points, pending the results of
  * internal asynchronous operations.
  * @param {Function} fn - Contains the body of the suspendable function. Calls to await()
  *                        may appear inside this function.
  * @returns {Function} A function of the form `(...args) --> Promise`. Any arguments
  *                     passed to this function are passed through to fn. The returned
  *                     promise is resolved when fn returns, or rejected if fn throws.
