FWIW (i.e. IMO the previous two functional solutions are better
examples) here is a more imperative style solution done sort of to
prove to myself that I could do such a thing in Clojure w/o too much
(arguable) fanfare. Maybe it will be interesting to others who are
learning Clojure too

It should just read `frames'.

It is hidden in Powerpoint slides (http://butunclebob.com/files/
downloads/Bowling%20Game%20Kata.ppt) linked on the description of the
bowling game (http://butunclebob.com/
ArticleS.UncleBob.TheBowlingGameKata).
Very nice! I would change the :satisfies clause for underachievers so
that it does not create an ordering dependency.
You should post this over on Uncle Bob's site.

Mark,
I think your approach is clean and simple, but loses the advantage of
decomposing the problem into useful constituent parts. I have written
this up in more detail at

Yo
My main concern was that the problem statement doesn't just specify
the score function but also a roll function to accumulate the ball
rolls. Obviously this will be different in Clojure since we would
prefer immutable data structures, but it feels like we're losing part
of the problem by ignoring
Sorry for the confusing choice of variable name. Should be "game" not
"games" in:
(defn score [game] (sum (take 10 (frame-scores game

Whoops, I guess I don't understand bowling scoring as well as I
thought. Now that I've read up a bit more on bowling scoring, I see
that if you get down to three rolls, (say 10, 7, 2) it must be scored
differently depending on whether it is a strike in the 9th frame
followed by 2 balls in the 10t
Hi Stuart,
Couldn't your frames function benefit from using (when) instead of (if)
(making it clear that the alternative is nil), and also, (when-let [rolls
(seq rolls)]) instead of just (when rolls), which may be more robust and
seems more idiomatic when used in conjunction with lazy-seq ?
BTW,
I think you guys are really overthinking this problem. Because
Clojure inherits Java's stack limitations, we tend to get hung up on
converting elegant recursive code into loop/recur/accumulator
structures. But here, we have a problem that we know isn't going to
blow the stack, so just think recu
