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.
