Michael, Is there anything I can do to help with 1946? It's now a month since I wrote that stuff and the more releases that go by before it is merged the harder it will be. Or will it be easier (for you!) to wait until 2.10.2 is released without it and then redo the patch based on that? John

OK, that makes sense to me (used to private data in C++ classes). Here the owning class is an ellipti curve, but I want points on that curve to access the private data. In C++ this would be done by decalring tha points were friends of curves. But here, I guess the correct thing is for other

You can use a single underscore to indicate private-ish, but not so private, e.g., change self.__order to self._order and then there will be no name mangling. But users still no they aren't supposed to muck with order. This is my preferred solution at all times. Nick
