The Fine Manual mentions that pickle works for classes that are defined at the top level of a module. Is there a way to extend this behavior so that I can pickle and unpickle instances of dynamically generated classes ?
Longer version: I have a function RecordTypeFactory(fields, ...) that dynamically generates and caches a record-like class based on the passed fields and other info (or returns the cached class if it has been created before). Although I am able to pickle instances of the various generated classes (records) by writing the gen. class in globals(), I cannot unpickle them from a different process unless RecordTypeFactory is called with the same arguments so that "the same" class is generated in the other process as well. Essentially what I'm missing is a hook to call RecordTypeFactory with the same fields when an instance of the gen. class is to be unpickled.
