Add Courtesy context.await function to Server Side Actions

Idea

I’ve been doing a lot of heavy lifting in back-end workflows. I’ve found I am repeatedly using the following pattern that mimicks the await operator:

// Make a promise
var holder = maker(... )

// Try to fulfil the promise
var fulfilment = context.async(
    callback => holder
    .then(fulfilled => callback(null, fulfilled))
    .catch(reason => callback(reason))
);

I was wondering if this could be fomalized into the context object:

context[await] = holder => !(holder instanceof Promise) ? holder : context.async(
    callback => holder
    .then(fulfilled => callback(null, fulfilled))
    .catch(reason => callback(reason))
);
