Can you please review the patch. It's not urgent. It adds additional tests for std??? == Py_None to some functions to speed up things or raise more meaningful exceptions when sys.std??? is None. |

The patch looks okay, but I just thought of something -- why not make sys.stdout and friends be undefined (i.e. NULL) instead of setting them to None? That way this patch isn't necessary and you only need one small change to builtin_print() -- which you need anyway (Try deleting sys.stdout and then printing something.) |

I prefer "if sys.stdout is None" over "if hasattr(sys, 'stdout'):" and "sys.stdout = None" over "del sys.stdout". I can't put words to it but it feels more natural to set the stream to None (NULL) than to incinerate the stream. IMO the problem warrants a short poll at Python 3000 dev. Christian |
