/**
* Handles overload methods (and dynamic class instances).
*
* @param string $method Name of a valid overload method to call upon.
* Or a dynamic class to return an instance of, using the special class `©` prefix.
* Or a dynamic singleton class method to call upon; also using the `©` prefix, along with a `.method_name` suffix.
*
* @param array $args An array of arguments to the overload method, or dynamic class object constructor.
* In the case of dynamic objects, it's fine to exclude the first argument, which is handled automatically by this routine.
* That is, the first argument to any extender is always the parent instance (i.e. `$this`).
*
* @return mixed Dynamic return values, or a dynamic object instance; else an exception is thrown.
*
* @throws exception If `$method` CANNOT be defined in any way.
