I think you mean "imports" in the marked case, right?

I prefer the order as given.  The export form is perhaps the more
interesting form, but it is also likely to be longer.  I suspect that the
import form will be no more than a few lines in most cases, and quite
often just one, but for large libraries, the export form could get pretty
long, burrying the import form.

I also think the import-export order is more intuitive.  The imports are
the raw materials, and the exports are produced from the imports.
