I need to treat file objects and sys.stdout object as one.
So I can write a class that writes likewise in a file
or to standard output.

The problem came when I called the close() method of an
sys.stdout object.
I've seen that in Pythonwin, sys.stdout has such a method.
This is not the case in the standard python.

And calling it causes that :

File
"C:\Python22\lib\site-packages\Pythonwin\pywin\scintilla\document.py",
line 153, in __call__
    return apply(getattr(v, self.name), (std, extra))
AttributeError: OnBraceMatch
win32ui: Exception in OnNotify() handler


I know that the right way to go is to avoid using the
close() method.
But methinks it's a bug that the method is available in
the IDE of pythonwin.

I was not completely right here, in console mode there is
the close() methode for sys.stdout object.
It's not the case in the IDLE !

Closing the stdout is not very helpful, as you will see
if you try it in the interactive interpreter.

Take a look at IDLE's PyShell.py for a way to use
Pseudofiles, this may help you.

We don't deal with Pythonwin.
