in thread Confused about splitting program into multiple files.

...if every function is going to be available (exported) is there a reason not to put them in package main?

One reason could be code reuse. If the same functions are used across several scripts, you at minimum save a little typing by keeping them in a separate file where they can be pulled in by all the scripts that need them.

    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.
