I've been planning to do this (making defsystem CLOS-based too) for over two
years now. The main impediment has been time; revising defsystem will take at
least a solid month's work, and I haven't been able to free up that much time.
But you're right -- ensuring compatability with 25 lisp implementations causes
lots of problems, especially when one tries to be clever and write a single
function to work in any of them.
