class C:

This is a point I was going to bring up.

The only wart is the necessity of mentioning the property name twice, once on the lhs and once as an argument. I haven't thought of a good solution to that, yet.

Have a look at my comment to Steven Bethard's recipe: http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/408713
