We have "import as", though. If you want to import the default
builtins without using them as the builtins, you can say
import __builtin__ as default_builtin
If you want to reset the builtins to the default builtins:
If you want to replace them with your own builtins:
import my_builtin as __builtin__
That doesn't seem so bad.
Hmm... when do you find yourself importing __builtin__?
