return latest value

[smmoosavi]

so we can get value in co-returned promise

var fn = co.wrap(compose(middleware));
fn().then(function (val) {
    console.log(val)
});

[jonathanong]

anyone object?

[jonathanong]

can you add a test for this?

[smmoosavi]

should I create same PR for next branch?

[jonathanong]

yeah that would be great
