How about >>> class A(object): ... def __init__(self): ... self._n = 0 ... @property ... def a(self): ... try: ... return self._n ... finally: ... self._n += 1 ... >>> import sys >>> sys.modules["yadda"] = A() >>> from yadda import a >>> from yadda import a as b >>> a, b (0, 1) Peter -- http://mail.python.org/mailman/listinfo/python-list
