I think requiring a ref could help with that: class Defer { private function __construct(private \Closure $callback) {} public function __destruct() { ($this->callback)(); } public static function _(\Closure $callback, &$var) { $var = new self($callback); } } $deferred = Defer::_($closeFiles(...), $foo); Without $foo there'd be an ArgumentCountError.
