If this is correct, than such a change (name of the type) may be > required to solve the regression between 3.3 and 3.3.1 Yes, but you're probably going to have to do more than change the class name in order for pickling to work for C types. Yes, of course. All of that is already implemented in patches Daniel Shahaf has submitted to the issue. The "controversial" question here is whether it's valid to change the module of the type between 3.3 and 3.3.1 ?

Failure to pickle suddenly is more of a compatibility issue IMO.
