[issue5370] unpickling vs. __getattr__

[Mike Meyer]

Mike Meyer <mwm at users.sourceforge.net> added the comment:

I don't believe in documenting bugs instead of fixing them. If this bug
is going to stay in the code, I can either fix my install of Python to
have non-broken Pickle modules, or I can fix every third-party libraries
objects I use whose authors didn't worry about pickling them enough to
find this. The fornmer is almost certainly easier, given a little time.
Probably even easier than agreeing on proper document wording.

The __init__ case is different - there isn't a common use case (this one
comes from the standard library) for __init__ that breaks pickling, and
the problems tend to manifest in the resulting pickles, not in the
unpickling process.
