All on mixins

I'm used to program to an interface, this makes my code loosely coupled and very extendable. Then I read about mixins and I started to frown. Mixins are classes that define and implement methods so they can be used to add methods on the fly to a new class. Sounds interesting doesn't it?

Now it sounds evil, doesn't it? My conclusion is that mixins are a great way to implement generic behaviour but overuse comes easily. Before using a mixin, try thinking of an alternative!
