Although what you're showing seems to be a variation on the curiously recurring template pattern, as the classes being mixed are listed 'symmetrically' without much regard for which will inherit from which. I found a blog post on 'mixin classes', which are like the CRTP but invert the inheritance relation. [1] What you've shown seems to be a third way.

yes, it's not proper CRTP but I did not want to spend too much time on that... just show that multiple inheritance has its uses even in fairly generic, non-OOP code :-)
