I'm using the "curry" recipe from the Python Cookbook (pretty much verbatim), and it appears to work fine in my code, but cPickle isn't happy about it:

The short answer is that Python doesn't currently pickle nested class and fucntion objects, i.e. those not defined at the top level of the module.

Unless something's changed since I last looked, you can't pickle functions at all.

def foo(): ... pass ... import cPickle cPickle.dump(foo, open('testpickle', 'w')) bar = cPickle.load(open('testpickle'))

I'd imagine this would work in most versions of python, given that people have been pickling objects for countless generations.
