Unless you're using Python 3, there's your problem right there. In Python 
2.x, properties only work correctly for new style classes, not classic 
classes. Change the above line to:

class Test(object):  # by convention, classes start with Uppercase.

and all should work (or at least you'll discover new and exciting 
different problems with your code).

which is more or less the same as inheriting from object, except uglier.
