Lambda the Ultimate Object

I am writing a book "Lambda the Ultimate Object". It's quite advanced at the moment, and already covers all the usual topics of OOP, though I'm still working on CLOS features that most other languages are lacking (I did method combinations, now working on multiple dispatch, then dynamic vs static dispatch, then the meta-object protocol). Feedback welcome.

I clicked the "submit" button, there was no feedback, so I clicked again many times, and it created many copies of the topic. Oops.
