I have a question to Rich - are there plans to introduce "named"

Nested loops work perfectly fine in Clojure:
Is this a recursive email? After receiving it seven times I've blown
my stack.
(defn print-pairs [seq1 seq2]
(loop [s1 seq1]
(when (seq s1)
(loop [s2 seq2]
(when (seq s2)
(prn (first s1) (first s2))
(recur (rest s2))))
(recur (rest s1)))))
(print-pairs [1 2] ["a" "b"])
I am not claiming that this is a good way to find pairs of items,
but it's an illustration for nested loops... recur always refers to
the innermost loop, so it can be nested to any level.
