Subject: [PATCH] Avoid warning with Elixir 1.3.1

Compiling 2 files (.ex)
warning: the variable "log" is unsafe as it has been set inside a case/cond/receive/if/&&/||. Please explicitly return the variable value instead. For example:

    case int do
      1 -> atom = :one
      2 -> atom = :two
    end

should be written as

    atom =
      case int do
        1 -> :one
        2 -> :two
      end
