I run into this problem often. I usually encounter it trying to make
independent modules A and B, which both depend on some directory. Or
even just around realizing users, I'd love to not worry about realizing
the same user twice.
Anyhow, it's imperfect, but you can check if something is defined, and
if it's not then define it.
