Ah, you may want to think about that a bit more. There's a reason globals are looked up when they're used rather than when their function is defined. Even in your own example, B isn't defined at all when you define A.

No, I'm afraid Brett is quite right. Globals are looked up when the function is executed, true, but they are looked up within the module that defined the function. Functions defined in _pypickle would only call the _pypickle version of functions.
