forEach with object + key in iterator about async

[caolan]

Yes, the reason being I didn't want to require each iterator to accept
the arguments: function (value, key, list, callback), since you
couldn't then just drop in some useful node.js functions. I
experimented with some variable callback arguments in nimble
(https://github.com/caolan/nimble), which allows you to iterate over
object properties in the way you describe but also allow you to use
the shorter syntax.

This is something I'd like to support in async in the future, but I
need to find a way that won't stop a lot of the standard node.js
library being useful as iterators.

You could start a new 'postfix', like a forEachAt(), or just eachAt() or something. Whole point for this one would be to have that list + key + value in the iterator so it sort of specifically would break pattern, and and this could indicate it maybe?

+1. I really need my keys :) Any plans to implement this? I could write a pull request.

I would also like this functionality. I think @Bartvds's way is least intrusive, but maybe use the Key postfix, like eachKey() and so on.
