"""
Test that files that define __all__ aren't missing any exports.

You can add names that shouldn't be exported to _all_ignore, like

_all_ignore = ['sys']

This is preferable to del-ing the names as this will break any name that is
used inside of a function. Note that names starting with an underscore are automatically ignored.
