PHP: Generator / Iterator support

[levu42]

I work a lot with generators and I often write code like

foreach($generator as $item) {
    ray($item);
}

so I would suggest something like ray()->iterateOver($generator); with a signature of iterateOver(Iterable $iterator, int $max=10).

What do you think about this feature, do you think it makes sense for me to submit a PR for it?

Seems interesting, go ahead!
