I understand you want the same behavior as the *property* when accessing
attributes (i.e. having a get, set and del method).
I am like you and I am about to propose a PEP just to say that properties
must be accepted in local() and globals() just the way they are in
attributes.

Something like :

>>> def myGet(self):
>>>	print "got it"
>>>	return "whatever"
>>> def mySet(self,value):
>>>	print "setting to",value
>>>	"whatever code here"
>>>	return None
>>>
>>> x=property(myGet,mySet)
>>>
>>> x
got it
whatever
>>> x=3
setting to 3
>>>
