If it were an object member you could use a property.
Does it need to be a module global?

In related news, can one make "properties" for modules? I was wondering
about this a month or so ago.

There have been various half-hearted requests for such a feature,
including by myself, but nothing concrete.

One day, in my Copious Spare Time, I intend to write a proper feature
request and/or PEP for such a feature. Obviously the absolute earliest
such a feature could be introduced is Python 3.4, about 18 months from
now. (Although frankly, I would imagine significant opposition from the
more conservative Python developers.)

Well these conservatives must have been suffering from chronic mononucleosis because i have never heard a peep from them! I wish they would "grow a pair" and speak up a bit more often because the language would benefit greatly from some austerity measures, strong leadership, and most of all; some Gawd damned consistency!
