You can easily subsume a promise (e.g., thenable — see Chapter 3) into a sequence using the instance method:

To adapt asynquence to systems using callbacks, there are several helper facilities. To automatically generate an “error-first style” callback from your sequence to wire into a callback-oriented utility, use :

Note: For the sake of clarity (and for fun!), let’s coin yet another term, for a sequence-producing function that comes from , like coolUtility here. I propose “sequory” (“sequence” + “factory”).
