Actually, that can be done right now as
self.x = x or 
I happen not to like it for some cases since
q = 
# Ah, ha! I still have a reference to the list through q!
assert obj.x is q
will raise an AssertionError.
if x is None: x = 
self.x = x
which would be written as
self.x = x if x is not None else 
with this if/else expression.
