Receive arguments from the resolved Promise in condition

[kevva]

When doing loops with HTTP requests, e.g. pagination, you need to check the response to decide whether to continue or not. Instead of defining a variable outside the Promise, it would be useful to receive the resolved value in the condition.

If you've left this out intentionally you can just forget about this issue :).

Seems like a valid use case to me.

Yup, valid use-case. Just didn't think of it when doing this module.

How should we do with the first call then? Should we force the user to check if anything is resolved in the condition (see example below), or should the first one run regardless?

pWhilst(res => {
    return res && res.next;
}, somePromise);

I think we should return undefined. We could also create a pDoWhilst or something :). Not sure though.
