Yeah, I think it 'smart'. Thanks for a nice solution.

Hi, all
I want some list functions in Haskell like mapAccumL in
clojure.contrib, because some sequence operations are difficult with
only functions in clojure.core and contrib.
Think about writing a function 'accum-seq', which takes a sequence of
numbers, and returns a sequence of numbers. Each e
