Although such a callable is probably intended to be called at some point, it is not necessarily called immediately, and it may be easier to track the source of it when you trigger the deprecation earlier. Example: ```php public function registerErrorHandler(callable $onerror) { $this->onError[] = $onerror; } ``` (Of course, this argument also holds for is_callable().) —Claude
