I see, so as long as there are no bool type hints for function parameters everything would be the same. This would lead to a minor asymmetry for $preserve = "yes"; if ($preserve) # Silently working, true array_slice($array, $offset, preserve_keys: $preserve)); # Not working any more I assume your solution would be to add an explicit cast to bool? i.e. something along the lines of array_slice($array, $offset, preserve_keys: (bool)$preserve)); # Explicit cast to silence implicit conversion I'm a bit worried about having to keep two different convert-to-bool rule sets in mind (implicit vs. explicit) and about the additional casts.
