Well, lambda's not going away[1], but there's no *need* for lambda here.
It could be written as::
class Base(object):
def __init__(self):
self.foo = None
def getFoo(self):
return self.__foo
def setFoo(self, val):
self.__foo = val
def _prop_get_foo(self):
return self.getFoo()
def _prop_set_foo(self, val):
return self.setFoo(val)
foo = property(fget=_prop_get_foo, fset=_prop_set_foo)
