That’s awesome timing! CLOS is such a fascinating topic. Enjoy getting into it, and feel free to comment if you have some questions or interesting discovery!
I think the CLOS is a very good OOP system. It's unfortunate that C++ and Java have implemented such schizophrenic notions of classes souring an entire generation on what OOP can be. I used functions quite heavily, but for stateful components in a system (especially when I want dispatch) CLOS is excellent. There are quite a few CLOS books too!
