Not sure I like this, it seems to be a semantic mess and a little too much Page object implementation related. Of course internally if the text attribute value is None this usually mean the page have not been loaded yet and practically it discard changes.

But imagine a user for whom the Page object is the representation of a Wikipage on server. He may have no idea of how the Page object is implemented. He may believe if he does this and saves the page he actually will blank the page on server when saving (actually if I read the code well it will raise an error in the site.editpage function)

Why not use something more explicit as a "discard_changes" function ? I don't really like the raw access to the attribute as it exposes some implementation details

Of course python has setter methods, but when I read

@text.setter

def text(self, value):

"""Update the current (edited) wikitext.

@param value: New value or None

@param value: basestring

"""

self._text = None if value is None else         unicode(value)

and

@text.deleter     def text(self):         """Delete the current (edited) wikitext."""               if hasattr(self, "_text"):                     del self._text

I find there is a lot of implicit for a pythonic program :) at least the meaning and the effects should be more explicitely documented.
