-  * Add a fourth optional parameter for spl_autoload_register called $types with the default value of T_CLASS (this would keep the BC), supported values would be any combination of T_CLASS and T_FUNCTION for now.+  * Add two new constants to spl: SPL_AUTOLOAD_CLASS, SPL_AUTOLOAD_FUNCTION.

     * As you would guess, this would work the same way as the $error_types parameter works for set_error_handler: you can specify for which type(s) of missing tokens the autoloader should be called.     * As you would guess, this would work the same way as the $error_types parameter works for set_error_handler: you can specify for which type(s) of missing tokens the autoloader should be called.
