The style guide says 'It *may* be easier' especially in cases where you ask "where did you come from?"'. I think that in this case, it is not easier, and the question "where did you come from?" will never be asked of the datetime object.

Most of the guide is stated in absolutes. This part of the guide is stated as a possibility ("may be easier"). I think from that difference in language, we can assume that this rule is not absolute, and is not intended to apply to every import, such as in cases like `nose.tools.eq_`.

Methods like `start()` are unclear unless you prefix them with `audio.` because there are so many methods named start. There aren't other things named datetime, so the ambiguity you are trying to guard against doesn't exist in this case.
