extend adds class methods too
Because classes are objects. So for example:
module Ispeak def says "greetings aliens!" end end module Ieat def eats "spinach" end end module Inhabitant def says "I'm strong to the finish" end end class Human extend Ispeak # add class methods from Ispeak include Inhabitant # add instance methods from Inhabitant end Human.extend Ieat # add class methods from Ieat puts Human.says # -> greetings aliens! puts Human.eats # -> spinach popeye = Human.new puts popeye.says # -> I'm strong to the finish
