Modern Common Lisp with FSet

> So FSet has a dual mission: first, to bring Common Lisp up to date, by giving it a much richer ensemble of functional collection data structures, to greatly expand the space of algorithms that can be written in an elegant functional style and still run efficiently; and second, as with Clojure, to support and encourage the use of functional collections for general programming.

Cool project but the docs could be greatly improved by putting the purpose of the project front and center. Don't make readers guess.
