Subject: Proc question (with Gtk Menus)

hello

yesterday someone posted this code in response to one of my questions:

require "gtk"
class SampleWindow < Gtk::Window
  def pn(msg)
    return Proc.new {puts msg,"\n"}
  end
  def initialize
    super
    items=[
          ["/_File",       nil,      "<Branch>",     nil,       nil],
          ["/File/_New",  "<ctrl>N", "<Item>",       pn("New"), nil],
          ["/File/_Quit", "<ctrl>Q", "<Item>",       pn("Quit",      nil],
.......

the 4th argument in the array has to be a function which returns a Proc

lets say I want to call this function also in another place and there it 
should be a normal function which does not just return a Proc object.

Is this possible??

when I change the function to
def pn(msg)
        puts msg
end

then the function always gets executed when I puts it in the array

maybe I am just blind or haven't understand how this Proc stuff really 
works?

please help. this drives me crazy :-)
