I was hoping that the dynamic creation of objects could be extended to support it's parameters in an array format like the functions call_user_method_array and call_user_func_array(). This would be great for test suites.
eg

function test_suite_object_test($class, $args) {
	if (!class_exists($class)) error();
	else {
		$obj = new_object_array($class, $args);
		...
		futher tests on the object
		...
	}
}

  This would useful, not having to hard code the constructors parameter
list, with obvious limitations, with something like:

function test_suite_object_test($class, $arg1, $arg2, $arg3, $arg4) {
	if (!class_exists($class)) error();
	else {
		$obj = new $class($arg1, $arg2, $arg3, $arg4);
		...
		futher tests on the object
		...
	}
}
