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.
