Common Lisp: Non-standard method combinations

In this video I just run through the use of a couple non standard method combinations, these are built in ways you can customize the way standard generic functions behave. I believe the full list is this: +, and, append, list, max, min, nconc, or, progn You can of course define your own, perhaps I will make a video about that. I have some other ideas for videos like doing a reading of some HP Lovecraft, obviously that is not programming related but I think it would be epic.
