Modules can return anything, or nothing (require converts this to true).

I've toyed with this idea as it does feel a bit silly to return a table with one function it it, but I always decided against it because:

1) I'll never be able to remember which modules return tables, and which return a function
2) I can guarantee that at some point in the future, that module which currently only has one function will need another, and the rewrite will be horrific if not returning a table.

Thanks,
