Probably a reduce is more appropriate.
(reduce
(fn [x a]
(your-compare-expression x a) ; the result of this expr is the result
of the fn and will be 'x' for the next iteration
)
0 b)
BTW, a let to bind an atom outside your do-seq, while _not recommended_,
should work. We would have to see your code to know why it didn't for
you. Show you code if you're curious, but please don't actually do it this
way.
