Yes, property is *NOT* a decorator, it can only be used as a decorator in
the one case that is mentioned in the docs:

<quote href="http://docs.python.org/lib/built-in-funcs.html#l2h-57">

If given, doc will be the docstring of the property attribute. Otherwise, 
the property will copy fget's docstring (if it exists). This makes it 
possible to create read-only properties easily using property() as a 
decorator: 

class Parrot(object):
    def __init__(self):
        self._voltage = 100000

    @property
    def voltage(self):
        """Get the current voltage."""
        return self._voltage

</quote>

Note the use of "read-only" in the above description and that the
decorated function (voltage) *is* the properties "fget" function.
