It seems that Python has some limitations regarding instance methods.
- Instance methods can't be copied.
- Instance methods can't be pickled.
This is problematic for me, because I work on a very object-oriented project in which I reference instance methods, and there's use of both deepcopying and pickling. The pickling thing is done mostly by the multiprocessing mechanism.
What would be a good way to solve this? I did some ugly workaround to the copying issue, but I'm looking for a nicer solution to both problems.
Does anyone have any suggestions?
Update:
My use case: I have a tiny event system. Each event has an .action
attribute that points to a function it's supposed to trigger, and sometimes that function is an instance method of some object.
