defmodule ReturnHelpers do
  @moduledoc """
  Simple library that adds a piping possibility for easy returning

  Imagine
  ```
    socket =
      socket
      |> assign(valid: true)
    {:noreply, socket}
  ```

  to write like:
  ```
    socket
    |> assign(valid: true)
    |> noreply()
  ```

  Looks cleaner ?
