set_global is undefined?

[slmjkdbtl]

Lua.State.new
    |> Lua.set_global(:a, 0)
    |> Lua.eval_file!("lib/test.lua")

says function Lua.set_global/3 is undefined or private

quick fix...
Need to change the dependencies instructions.
The installation instructions still refer to version 0.3.0 which is not what is on the master branch and to which all the Functions described refer to...
So need to change that to

{:exlua, "~> 0.4.0-dev"}

or this

defp deps do
        [
                {:exlua, github: "bendiken/exlua", branch: "master"},
                {:luerl, "~> 0.3"}
        ]
  end
