I guess the library overhaul hasn't really started it but it would be nice if the pickle module could get some work. Today I'm trying to efficiently store a class using pickle and the documentation is making my head hurt. I don't think the documentation itself is the problem, just the fact that the rules are so complicated.
I guess there are several different solutions:
* Remove backwards compatible stuff from the code and the
documentation. The downside is that old pickles could not be
loaded. Perhaps that's not a huge issue since the removal of
old-style classes might already break old pickles.
* Remove the backwards compatible stuff from the documentation
only. The would help people using the language but would
still be a long term maintenance issue.
* Leave the old code in but generate warnings when old pickle
mechanisms are used. Eventually the old stuff could be
removed from the code.
* Provide an "oldpickle" module the supports pre-3k pickles.I think I like the warnings idea best.
