Re: array_reject() as counterpart of array_filter()

Just to confirm array_filter(“!is_int”, $collection) Would result in a collection of only non-integers?? I do think there’s something to be said for the communication of intent without syntax. array_without or array_reject reads easier to me than making sure to watch for the bang.
