The analogy was including a mixin (seen as a collection of methods) in different classes and including a single method in different classes. I never compared a module with a class. But I see what you mean. The methods in a mixin should be designed to work in multiple classes, and methods in a class shouldn't (necessarily). True, but there's a "should" on both sides. My point was the "should". What you seem to be saying is that no method in any class could possibly ever work in any other class. Peter
