I like types :D Makes understanding what is going on in structs way easier.

defmodule Examples do
  defstruct first: nil, last: nil

  @type t(first, last) :: %Examples{first: first, last: last}

  @type t :: %Examples{first: integer, last: integer}
end

As an example. Makes thing easier if you choose to run https://github.com/jeremyjh/dialyxir
