|

 ?\s for space
 ?\t for tab
 ?\n for newline

|2) The function and subscription operators: how can I overload

Sorry, you can't. Proc and Method imitate it by call or [].

  class Function
    def call(*args)
      ...
    end
    def [](*args)
      ...
    end
  end

  f = Function::new
  f.call(1,2,3)
  f[1,2,3]
