You want to import a name that is itself a namespace; preferably a module or package and sometimes a class.

The idea behind constants is that they are... um... constant. ;) I imagine exceptions don't get changed often either. (At least, I never change mine.)
If you have a setting that may change, don't call it a constant and name it accordingly.
