TIL: Anonymous Functions Can Have Multiple Heads

There is no need to use case inside of anonymous function - instead, we can create function with multiple heads.

list = [1, 2, 3, {4, 5}, 6, {7, 8}]

Enum.each(list, fn
  {first_value, secon_value} ->
    IO.puts("Tuple: #{first_value}, #{secon_value}")

  element ->
    IO.puts("Simple element: #{element}")
end)
