 Well try this

moulon% cat b.rb
#!/usr/bin/ruby

module TheModule
   def self.foo123
      puts "Doing stuff..."
   end

   private
   def foo123
      puts "I'm the private method doing stuff..."
   end
end

include TheModule
TheModule.foo123
foo123
self.foo123 # will give an error because it's a private method
moulon%
 
moulon% ./b.rb
Doing stuff...
I'm the private method doing stuff...
./b.rb:17: private method `foo123' called for main:Object (NoMethodError)
moulon% 


 module_function define a public singleton method and a private method.
