(In Ruby) allowing mixed-in class methods access to class constants

Question

I have a class with a constant defined for it. I then have a class method defined that accesses that class constant. This works fine. An example:

#! /usr/bin/         


        

Answer 1

This seems to work:

#! /usr/bin/env ruby

module CommonMethods
    def shout_my_constant
        puts self::Const.upcase
    end
end

class NonInstantiableClass
    Const = "hello, world!"
    class << self
        include CommonMethods
    end
end

NonInstantiableClass.shout_my_constant
