I'd be happy to proclaim that doing something like

import X d = X.dict d["spam"] = 42 # or exec "spam = 42" in d is always prohibited. That would break lazy module imports such as the one I'm using in mx.Misc.LazyModule.py. But you could rewrite LazyModule.py to use setattr(X, "spam", 42), right?

Sure.

I don't think it's worth it to have a dict proxy that allows certain keys to be set but not others.

The question is: why make this complicated ?

If the programmer enables fast_builtins (or similar) in the module scope, she should be aware that tweaking the module globals from the outside won't have the desired effect.
