@Reuven It's also a violation of the Zen of Python - "namespaces are one honking great idea -- let's do more of those"!I'd also add that sometimes you want to do this within your own packages - like keeping all the magic constants in a sub-module, but you don't want to have to refer to them as `constants.foo` all through the rest of the code. In this case, use the `__all__` definition in constants.py to explicitly export only the names you want used this way.
