I think you missed the point here. We are already discussing a separate module that can be used by any script. The question is, if that module exports every function within, why not simply make the package name 'main' and not bother exporting?

The answer is: because that forces your decision upon all users of the module. If you at least use a separate package name I can avoid your auto-exportation of everything by doing: use YourMod();. Or maybe I want to use your module from another package (have your module export into a different namespace). If you write your module to simply define everything inside of package 'main', you've removed all my options.
