> Sure, modules provide a way to "package" functions, but that is 5% of what a package manager does. Being able to distribute, fetch and do dependency resolution is certainly the bulk of it.

Please God the Erlang/Elixir community don't invent another package manager. Pip, easy_install, gem, npm, composer, bundler, bower, maven and all the others I don't know about - we've got enough as users to remember the variations in syntax for. Let alone the duplication of effort in developing and maintaining the package managers, when their clever creators could be working on other problems.
