Thank you -- I'll check it out. I'm familiar with CLOS, but I have never looked seriously into implementation strategies. I have read many research papers on compiler design, language design, (multiple)dispatch implementations, and I have concluded that the languages we use day-to-day are decades behind what we would be using if we took advantage of this research.
