Solve alias problem in Elixir

Recently, I must type too much for alias Module for using short name in code(Module name in Elixir is quite long). Problem here is I need to repeat that action over and over.

When posted a proposal for solve this problem I receives an advice very valuation from community. I repost the idea in here for people can read and solve problem if that problem is like mine.

Define a macro and function for supporting centric all aliases like:

defmodule Namespace do
  @moduledoc """
    This module provides a way to define a namespace for a set of modules.
    It can be used to define a set of modules that share a common prefix.

    This version only support for native atom not a alias.

    # usage
    ```


    use Namespace, DataSpace


    ```
  """

  defmacro __using__(namespace) do
    Namespace.get(Macro.expand_once(namespace, __ENV__))
  end

  def get(Suppliers) do
    quote do
      alias MyApp.Domains.Suppliers
      alias Suppliers.Hotel
      alias Suppliers.Transport
      alias Suppliers.Restaurant
    end
  end

  def get(Customers) do
    quote do
      alias MyApp.Structs.Customers
      alias Customers.Address
      alias Customers.Details
    end
  end
end

In other module I can use like:

defmodule MyApp.Data.Processor do
  use Namespace, Suppliers

...

end

This way help me provide a centric way and clean code for alias and avoid to repeat add alias ... action.

Downside of this way is compiler is warning if an alias is unused.

Original idea is from post in Elixir community
