 module_function make a private method and a public singleton method.

W>     def bar()
W>       "baz"

W>   end

 For example


svg% cat b.rb
#!/usr/bin/ruby
module A
   def a
      puts "a"
   end
   module_function :a

   def self.b
      puts "b"
   end
end

A.a
A.b

include A
a
b
svg%
 
svg% b.rb
a
b
a
./b.rb:18: undefined local variable or method `b' for main:Object (NameError)
svg%
