That’s interesting as I haven’t played with iterates and generators much.
If the iterator can’t take an iterable, the idea of something like __toArray
seems way more convenient: https://wiki.php.net/rfc/to-array

I have a draft RFC (https://wiki.php.net/rfc/foreach_void) and patch
I would highly prefer php optimalization for it. ArrayKeysIterator can
not even used if the input is iterable instead of pure array.

Optimizing foreach (array_keys($arr) as $k) is very important, not only
because of memory, but because of speed when not all elements needs to
be iterated, like:
foreach (array_keys($arr) as $k) {
if ($k some condition) {
break;
}
}
please, can someone send a PR for this?
NB: You have SplFixedArray which can cover some use-cases.

I'm looking forward to an answer from someone proficient in this area
because _I think_ the engine _internally_ keeps track of
