iterator_count signature for iterables

Hello internals! Currently, iterator_count has the following signature: iterator_count(Traversable|array $iterator): int If we try to use iterable type and pass it to iterator_count function, we'd get following static analysis error: Argument 1 of iterator_count expects Traversable|array<array-key, mixed>, but iterable<int, list<string>> provided (see https://psalm.dev/004) $start(iterator_count($chunks)); From what I know, iterable is just built-in compile time type alias for array|Traversable (https://www.php.net/manual/en/language.types.iterable.php) I think it would make sense to change the signature of iterator_count to accept iterable rather than array|Traversable so that static analysis tools would pick it up better
