The problem is that map returns a lazy seq, and the lazy seq is
evaluated outside of the binding by the REPL. If you add a doall
inside the binding, it behaves as you expect.

Now, these are finite examples. If you wanted an infinite lazy seq,
you could substitute (interate inc 1) for (range 10). Just be very
careful evaluating this at a REPL.

(keys (group-by...))
(map first (vals (group-by ...)))

You're still better off w/ group-by, and manipulating the resulting

PersistentTreeSet delegates a lot of work to PersistentTreeMap, so the

I think the fns you're interested in are sort and sort-by, not sorted-
set-by.
I know you might not like it, but there is a convention in JavaLand
that a comparator value of 0 is identical in a sorted collection.
This causes orthogonal concepts of order & identity to be entwined.

Hmmm... I'm not sure destructuring is possible here. Would it be
easier to put an extractor fn in place?
(defn extract
[arg]
(apply hash-map (map (juxt :tag :content) (:content arg
Just a thought. I'm sure someone will have a better idea, though.

If you're gonna over engineer use a protocol :-p

At first glance, you should be requiring c.c.string, and don't write
your own blank? fn. That's the only low hanging fruit I see.

Hmmm... we could talk about what's faster or measure it. Time to eat
my own damn dog food, I guess :)
Traveling now, I'll run the experiments in a few days when I get back
to my normal setup.

If you've got the HD space, grab the most inclusive options. I
*think* the SE one will work, but I haven't tested it. Space is cheap
and all that.

And then we just spit this into a file:
(spit "output.txt" (join "\n" (map #(join " " %) raw-vec)))
And that should do it :)

Is there a built in to insert a value into an "indexed" seq?
For example:
user=> (insert [:a :b :c :d] 2 :q)
(:a :b :q :c :d)
Not sure if I'm missing something simple...

Also, why does this work:
user=> (assoc [:a :b :c :d] 2 :q)
[:a :b :q :d]
And this doesn't:
user=> (dissoc [:a :b :c :d] 2)
#
Annoying.

ong tool for the job. However, there are still problems
that require me to use an expensive operation.
Maybe I'm too focused on my current project, and wrong about how much
a typical person would use insert. Still, its absence seems like an
oversight.

largh.
Why doesn't this work when I use send? I'm at a loss here.

Right...
Is there a way to force an agent thread to be evaluated in a certain
namespace?
You see, the current design accepts a string, and uses read-string to
parse it. i.e. I call a form like this a lot
(send test-query conj (read-string (get-input)))

Okay, found a fix do my own bug. You can use the with-ns namespace to
solve this issue. I changed the form to be like this:
(send test-result
(fn [& args] (with-ns 'my-ns (eval `(->> ~@(deref test-query))

I'd use the built-in, partition
user=> (partition 2 (range 1 9))
((1 2) (3 4) (5 6) (7 8))
And add a mapping operation
user=> (map vec (partition 2 (range 1 9)))
([1 2] [3 4] [5 6] [7 8])
Am I missing a requirement?
