Ben,

Do you mean this, or are you looking for something more subtle that
I'm (yet again) missing.


    def empower(anObj)
       def anObj.gotThePower?
         puts "I feeel the power"
       end
    end

    a = "downtrodden"
    empower(a)
    a.gotThePower?   #=>  I feeel the power


Regards


Dave
