Hi internals,

I'd like to propose opening an rfc to make the following syntax legal:

foreach($array as (int) $i) {}

Which would be functionally equivalent to

foreach($array as $i) {
$i=(int) $i;
}

Thoughts? Feedback?

Cast would work for both key and value, although I think the instances
where you need to cast a key will be fewer.

what about:

foreach($array as $i=>$v) {}
