Based on the testability comments in the closure threads, I created http://bugs.python.org/issue13062 to propose two new introspection functions: inspect.getclosure(func) Returns a dictionary mapping closure references from the supplied function to their current values. inspect.getgeneratorlocals(generator) Returns the same result as would be reported by calling locals() in the generator's frame of execution The former would just involve syncing up the names on the code object with the cell references on the function object, while the latter would be equivalent to doing generator.gi_frame.f_locals with some nice error checking for when the generator's frame is already gone (or the supplied object isn't a generator iterator).
