Nested modules suggestion?

It sounds like you are calling a function like this:

defmodule Mix.Tasks.Deploy do
  use Mix.Task

  def run(_) do
    # doing really cool stuff
    # ...

    Comeonin.Argon2.hashpwsalt("some password")

    # ...
    # more cool stuff
  end
end

What credo is suggesting is to do something like this:

defmodule Mix.Tasks.Deploy do
  use Mix.Task
  alias Comeonin.Argon2

  def run(_) do
    # best programming you have ever seen
    # ...

    Argon2.hashpwsalt("bestpassword")

    # ...
    # more cool programming
  end
end

So, credo is complaining that you are calling a function with nested module names, Comeonin.Argon2.hashpwsalt/1, for example. It wants you to call a function with a singular module name, like Argon2.hashpwsalt/1. So you can use alias for this purpose. The cool think about alias is that it is lexically scoped. This means you can use it within a function :exploding_head: if you need.
