Hi,

What about ModuleProxy?

From the dictionary:

prox·y /ˈpräksē/ Noun The authority to represent someone else, esp. in voting. A person authorized to act on behalf of another. Synonyms deputy - representative - agent - substitute

See http://bugs.python.org/issue18088 for the other part of this story. I'm basically replacing what importlib.util.moduleforloader does after I realized there is no way in a subclass to override what/how attributes are set on a module before the code object is executed. Instead of using the decorator people will be able to use this context manager with a new method to get the same effect with the ability to better control attribute initialization. (FWIW, I think "ModuleManager" is a rather bad name :-) +1. XxxManager is what Java programmers call their classes when they are forced to have an unnecessary class because they don't have 1st class functions or modules. (I don't like 'Context Manager' either, but it's too late to change it :( ) I'm open to suggestions, but the thing does manage the module so it at least makes sense. But what do you mean by managing? 'Manage' has many meanings. Once you've answered that question you should have your name. Cheers, Mark.
