FWIW, there's also a hack without java calls, which Chouser referred
to:
(binding [*ns* (find-ns 'foo)]
(eval '(def bar 3)))
although you have to create the namespace yourself if it doesn't

Guys, thanks for all the answers. I was posting my follow ups to this
thread via Gmail until I realized that Google Groups was bouncing my
posts. @#$! Anyway, I used a ref to store my function instead of
defn'ing it. Macro expands to
(dosync (ref-set fun (fn [] ...)))
Great to hear Stuart! I've been very happy with the book so far (it's
lived up to the Pragmatic title) and am very much looking forward to
the new betas.
Just wanted to send my thanks to Rich for developing Clojure and to
Stuart for the great book. Keep up the great work!

the symbol provided, e.g.:

Ah, yes. I meant, what are these hints? What does the compiler change?
Is it some sort of informal type enforcement or something?
The hints are described here:

It is strictly a performance
Nevermind. I see it's fixed in the latest code in svn.
