What is a reliable way to get the
the property object for an instance attribute?
(Or more generally, to get the descriptor
controlling an attribute?)
If class ``A`` defines the property ``x`` and ``a``
in an instance of ``A``, then you can just use
``type(a).__dict__['x']`` to get the property object.
But this will not work if the property is inherited.
type(a).x
py> class A(object):
... def getx(self): return 1
... x = property(getx)
...
py> class B(A):
... pass
...
py> b=B()
py> b.x
1
py> B.x
<property object at 0x00B8A690>
py> type(b).x
<property object at 0x00B8A690>
py> getattr(type(b),'x')
<property object at 0x00B8A690>
py>
