Dynamically add module functions in __using__ macro

Questions & Help Questions

I’m pretty sure you can just import the parent module of the __using__ macro with import A inside the macro. For example, the Phoenix 1.3 generators create the following DataCase module:

defmodule MyApp.DataCase do

  using do
    quote do
      ...

      import MyApp.DataCase
    end
  end

  def errors_on(changeset) ...
end

So, all of the MyApp.DataCase functions will be auto imported into the scope of any module which calls use MyApp.DataCase.
