It is not wrong from a syntax point of view, but it is wrong because it
assumes doctest is a sub-module and not a sub-package. As said here:

    http://docs.python.org/tutorial/modules.html#packages

It would have been perfect to write:

import zope.testing.doctest

... avoiding the "embedded" design decision that doctest is a sub-module.

Anyway, I'm happy with whatever fix we apply, as long as we find a way to
not rise the deprecation warning just after an import of zope.testing or a
run of the testrunner.

No, because modules/packages are imported only once.

I thought we deprecated the whole zope.testing.doctest.

Best regards, and Merry Christmas.
