Summary: Polymorphic getters / setters

Initial Comment:
If you add a property to a class with a getter and/or
setter and override the getter and/or setter in a
subclass the baseclass implementation of the methods is
still called when the property is accessed on objects
of the subclass.

class base(object):
  def get_foo(self):
    print "Base get"
  def set_foo(self, value):
    print "Base set"
  foo = property(get_foo, set_foo)

class sub(base):
  def get_foo(self):
    print "Sub get"
  def set_foo(self, value):
    print "Sub set"
 
s = sub()
s.foo = s.foo

-- Prints:

Base get
Base set
