At that point, it doesn't matter. It only matters when you go to
use it. However you organize the block of imports at the top
of the file will usually work; if there's a lot, I find alphabetizing
them sometimes helps, or sometimes putting the standard ones
first.

The one caveat to that is with modules that have circular
dependencies, but that's a whole different set of problems than
the one I think you're talking about.
