Just for the record, Clojure does support local variable that behave
exactly as you would expect them:
(with-local-vars [x 3]
(while (> @x 0)
(var-set x (- @x 1)))
@x)
-> 0
Using an atom is unnecessary in this case because access is totally
local. Using an unsafe atom set is a bad habit, as discussed in detail
on another thread:
http://groups.google.com/group/clojure/browse_thread/thread/6497e7c8bc58bb4e/c5b3c9dbe6a1f5d5
However as you have already seen there are more elegant ways to write
the solution without either.
