[Python-ideas] Callable properties

[George Sakkis]

I'm wondering if there is any downside in making properties callable:

class callableproperty(property):
    def __call__(self, obj):
        return self.fget(obj)

class Foo(object):
    @property
    def bar(self):
        return self

    @callableproperty
    def baz(self):
        return self


>>> foo = Foo()
>>> foo.baz is Foo.baz(foo)
True
>>> foo.bar is Foo.bar(foo)
...
TypeError: 'property' object is not callable


As for the motivation, having callable properties would make it easier
to stack them with other decorators that typically expect callables.
Am I missing something ?
