ok, let me try this again, sans distractions:
could we consider adding __code__ and __call__ to module objects?
__code__ would contain the code executed in the module __dict__, and __call__ would reload the module.
thoughts?
The question to ask is: what would such a change make possible that importlib doesn't already handle? This specific proposal wouldn't work right for extension modules, so people will still need to go through the importlib APIs anyway. If you haven't seen it yet, you may also want to give PEP 451 a read - we already overhauled several aspects of the import system for 3.4. Cheers, Nick.

hello,
could we make modules work more like this...
https://gist.github.com/xtfxme/9556806
tl;dr: __code__ object available (potentially a __self__ object), reload
by calling, makes working with modules more natural/safe!
