Mmmm, I might still miss something. OK, I can replace my initial
property using @property and @p.setter, but it doesn't seem to work in
subclasses:

class A(object):
  @property
  def p(self):
    return self._p
  @p.setter
  def _set_p(self, p):
    self._p = p
class B(A):
  @p.setter
  def _set_p(self, p):
    …

results in:

Traceback (most recent call last):
  File "toto.py", line 8, in <module>
    class B(A):
  File "toto.py", line 9, in B
    @p.setter
NameError: name 'p' is not defined
