module Test

    'x'

  def y arg
    arg + 'y'
  end

  module_function :get
end

puts Test.get

10:31 $ ruby test.rb 
test.rb:3:in `get': undefined local variable or method `x' for Test:Module (NameError)
        from test.rb:18:in `<main>'

if I don't want to use Classes in ruby but want to have just collection of functions (some exposed as public and some for internal use only), am I totally doomed? can't find the way to do it

Ok. I am doomed to use class

module Test
  class << self
    def get
      y x
    end

    private

    def x
      'x'
    end

    def y arg
      arg + 'y'
    end
  end
end


puts Test.get

10:50 $ ruby test.rb
