What if, instead of trying to annotate the module object with this 
assortment of metadata - metadata which depends on lots of things, and 
can vary from interpreter to interpreter, and even from module to module 
(depending on how it was loaded) - we just stuck with the __loader__ 
annotation, and encouraged/allowed/facilitated the use of the loader 
object to learn all of this extra information?
