Another proof:
Let study the sequence sn = 0....9 , with n 9s.
Or s0= 0 and s(n+1) = sn + 9 / 10 ^n

Interesting approach. I'll keep it in mind, but for this particular
project I actually have to have mutable objects - both parents and
children must be modifyable. Also I really want to see them as
collections: closures where used everywhere in the previous version of
program, and it was very hard
Oh, I think I missed your suggestion of multimethods. They do in fact
look pretty interesting, but I wasn't able to figure out how that would
solve my problem - they look more like overloading than polymorphism to
me. Would you mind posting a variant of my example that uses multimethods?

For the sake of comparison with other LISPs - some Scheme
implementations have an exact? function for dealing with non-precise
numbers.
This seems not to have come across to Clojure. (Although we do have
ratios and BigInteger).

You have a normal tree, and then you have a map where

Hi All,
In Python I was used to be able to easily create dictionaries from
lists of key value 'pairs' (tuples or list), e.g. like this:
dict([(10, 20), (30, 40)]) #using the dict constructor
=
{10:20, 30:40}
What would be the equivalent in Clojure?, e.g. the normal Clojure hash-
map function
Here's one approach:
(into {} [[:a 1] [:b 2] [:c 3]])
= {:a 1, :b 2, :c 3}

Since no one chimed in with support or reasoning for resultset-seq's
current lower-casing behavior, can we discuss changing it to
case-maintaining behavior, or at least make it something you can set

I need a function that produces the 'next' value from a lazy-seq --
something like a Python generator. I imagine it would have to be some
sort of closure like:
(def next-sine
(let [sines (atom (cycle (map sin (range 0 6.28 0.01]
#(swap! sines rest)))
Is there a more idomatic way
Maybe something like this. Those calls polymorphic on the returrn
value of the anynimous function, so this is more powerful than
overloading.
(defmulti load-page (fn [p n] (:id p)))
(defmethod load-page :db [loader name] (println db provider for page
name))
(defmethod load-page :fs [loader name]
This is fantastic! Does it work reliably for most JDBC drivers? Some
drivers may not implement meta data API very well, and some drivers
may have their own idiosyncrasies. You can perhaps setup a GitHub
project and push to Clojars if this doesn't get into contrib any time
soon.

Are you sure you need to capture the state in next-sine? It's not very
clojure-ly to have functions with state. I would capture the state in
the caller as an integer and just use get or nth on the lazy seq.
If you want to stick to your impure function, please mark it with a !

I have made
(defn iterate [s]
(let [a (atom s)]
(fn []
(let [s @a]
(reset! a (next s))
(first s))
but it's not very idiomatic in clojure.
(In Lisp it is traditional to hide a state in a closure. A lot of toy
object language work like that)

I have recently looked at mongodb and liked the idea of a schema less

- lots of reflection warnings
- perhaps lacking some finish...

At a different level. (dotimes [n 1] (for ...)) does evaluate the for form.
But it returns a seq which is never realised. So you do effectively … nothing.
(dotimes [n 1] (into [] (for ...))) as in your example
Yes, it would be. But it's wildly unlikely that you need to do it.
You don't say what you're using next-sine! for, but I'll imagine
you're doing something like printing it. Maybe your code looks like:
(dotimes [n num-iters]
(let [s current-sine]
(next-sine!)
(println s)))
This can
I wouldn't say it has *nothing* to do with dotimes. If dotimes were
lazy rather than eager, then his form would do nothing despite the
eagerness of into, because into is not being called:
(for [i (range 100)]
(into [] (some-expensive-calc)))
