But wouldn't this mean that those properties would no longer be available in the module's __dict__?
Correct. Module properties would behave exactly like instance properties. They don't appear on the instance's __dict__ attribute, too.
By the way I was astonished that the vars() function dones't show properties but dir() does list them.
"Astonished" sounds stronger than you probably meant it. :-)
class Example(object): ... @property ... def x(self): ... return 42 ... example = Example() example.__dict__ {} vars(example) {} dir(example) ['__class__', '__delattr__', '__dict__', '__doc__', '__getattribute__', '__hash__', '__init__', '__module__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__setattr__', '__str__', '__weakref__', 'x']
They are intentionally different though -- dir() tries to give all the attributes, while vars() only accesses __dict__. -- --Guido van Rossum (home page: http://www.python.org/~guido/)
