+1.
Twisted actually tried to preserve pickle compatibility in the bad old
days,
but it was impossible. Pickles should never really be saved to disk
unless
they contain nothing but lists, ints, strings, and dicts.
But what is alternative in stdlib?
Don't you think that Python doesn't provide any?
Persistence is a very hard problem. Lots and lots of trade-offs need to
be made, and you generally want to tailor those trade-offs to the
particular application at hand. This probably means that the stdlib
isn't a suitable place to try to solve the problem.
Look outside the stdlib and you'll find an extremely vibrant and diverse
collection of software which is aimed at solving this problem, though.
