Wow! Now this is weird!

I honestly don’t know what to make of Clojure’s ad-hoc hierarchies. I have, I confess, been missing a little bit of the polymorphism I’m used to with classic OO class-hierarchies.

This looks like it’s the answer to that. But hmmmm …. if I start down this path am I going to find myself reinventing standard OO capacities with a weird syntax? Does adopting these things mean I’m falling back from my FP sophistication to “class-based” programming? Is it the equivalent of abusing do to make my Lisp more imperative?
