This doesn't really solve the problem imo. Imported symbols shouldn't be i portable elsewhere. Not by import * or explicitly. That's the problem.

I do not think that this is always a problem. It is common to refactor the code by defining names in submodules and then importing them in the main module. For example, in `json/__init__.py`:

from .decoder import JSONDecoder, JSONDecodeError from .encoder import JSONEncoder

It is possible even to use a star import.

So this change would break much more code.

I believe I covered that in my last email. I'll repeat it here for clarity: if you indent to re-export you can do that explicitly: from foo import bar bar = bar For "from x import *" you'd need to iterate over __import_dict__ (or whatever we call it) and set them all. / Anders
