No, I don’t expect all objects to have the same properties. So, today I learned that `$foo = 1; isset($foo->bar);` doesn’t throw an error about a non-object. However, property_exists *does* throw errors in that situation, as does get_object_vars() - two situations where you *can* pass any object, so long as it is an object.
Like I said, the functionality is possible without it. But what functionality was impossible without int/float/string type hints? They just make it much clearer, with less repeated boiler plate, what arguments you can actually accept.
