Transfor function between different and run

function_transfor.ex

1.Demo how to transfor function
2.Demo how to construct function and call it
3.& capture operator will conver Module.Function/arity to lambda
4.& capture operation could be also used to shorten lambda

defmodule FunctionTransfor do
  @moduledoc false
  def display(msg), do: IO.puts msg
  def add1 do
    fn(x)-> x + 1 end
  end
end

defmodule Profile do
  def run(fun,msg) do
    fun.(msg)
  end
end

#Test case
#Profile.run(&FunctionTransfor.display/1,"hello")
#Profile.run(fn(msg)->IO.puts msg end,"hello")
#Profile.run(&IO.puts/1,"hello")
#Profile.run(FunctionTransfor.add1, 1) == 2
#Profile.run(&(&1 +1), 1) == 2
#apply(FunctionTransfor, :display, ["hello"])
