 |         # the bug: | 
 |         # when converting curses.window.addch to Argument Clinic | 
 |         # the first two parameters were switched. | 
 |  | 
 |         # if someday we can represent the signature of addch | 
 |         # we will need to rewrite this test. | 
 |         try: | 
 |             signature = inspect.signature(stdscr.addch) | 
 |             self.assertFalse(signature) | 
 |         except ValueError: | 
 |             # not generating a signature is fine. | 
 |             pass | 
 |  | 
 |         # So.  No signature for addch. | 
 |         # But Argument Clinic gave us a human-readable equivalent | 
 |         # as the first line of the docstring.  So we parse that, | 
 |         # and ensure that the parameters appear in the correct order. | 
 |         # Since this is parsing output from Argument Clinic, we can | 
 |         # be reasonably certain the generated parsing code will be | 
 |         # correct too. |
