Meaningful module names in Elixir

Just a reminder that you don't need to restrict yourself to Pascal case for module names.

If you like consistency and think module names should look like function names, don't think twice!

defmodule :snake_case, do: nil

If you like symbols, you have a lot of options!

defmodule :::, do: nil
defmodule :.., do: nil
defmodule :@, do: nil
defmodule :<, do: nil

Or even

defmodule :., do: nil

And don't forget about custom operators! You can get really fancy here:

defmodule :. do
  def a +++ b, do: a + b
end

iex> :".".+++ 1, 2
3

Or maybe

defmodule :>>> do
  def a >>> b, do: "brrr"
end

iex> :>>>.>>> 1, 2
"brrr"

Finally, don't:

defmodule APerfectlyFineModule do
  @moduledoc "Here be dragons"
end

This is just too easy to miss. Instead, do:

defmodule :"Here be dragons", do: nil
