I tend to agree with Nick though I like the explicitness of #1.  I
have just been reading some old code today and I wish it had all been
done like #1, it would have helped my brain quickly understand exactly
what was going on without jumping around.

Actually, I think I would avoid #4 too, just to save myself the mental
substitution of the real package.module.  It may save you a bit of
effort when you write it, but if you ever have to go back and read it
again, #1 will make understanding it easier.
