Like the doc says, `with-query-results` takes additional options
before the query string.
In your case, it should be something like this:
(sql/with-query-results recs
`[{:fetch-size 1000} ~query-str ~@bvs]
(doall recs))

Oh, thanks for the explanation.
I looked at the twitterbuzz code before replying, saw the function
calls with arguments written the usual way, and (erroneously) decided
it would be the same for the zero-arity calls. But it's there in the
wiki.

When I do that, the REPL starts printing the sequence, filling screens
after screens with numbers.
By doing that, it realizes the printed part of the sequence, which
will eventually lead to an OOM error, since it probably holds on to
the reference to the start of the sequence.
Doing (set! clojure.

This should be equivalent to (def iframe (.getEditableIframe field))
which is the usual way to do method calls on the host langua

It's not supposed to, see the doc. To do full expansion, you can use
`clojure.walk/macroexpand-all`.

This would be a straightforward solution:
(defmacro when-lets [bindings & body]
`(let ~bindings
(when (and ~@(map first (partition 2 2 bindings)))
~@body)))
It works well in simple cases, but breaks e.g. in case of parameter
destructuring.
If you read `(source when-let)`, you'll see
Type annotations are used at compile time to generate direct method
calls (as opposed to using reflection).
`cast` is a function, so it doesn't do anything until runtime, and it
just delegates to Class#cast.
I don't think it is used much. In the core, it's only called in single-
arity cases for *

Ahem.
Here is a more idiomatic version that runs under half a second, no
annotations required.
(def vs (atom {}))
(defn sk [k]
(if (@vs k)
(@vs k)
(let [ans (if (< k 56)
(- (mod (+ 13 (- (* k 23)) (* 37 k k k))
100) 50

In case the two replies above didn't drive the point home, the Python
version is not recursive (it uses results memoized in the data array).
So, not the same thing.

The first version stops as soon it encounters the first item in the
collection that's too big.
The second version filters the whole collection, which may lead to a
major slowdown, depending on coll's relative size. It will also hang
if coll is infinite.
This should be better: (take-while #(<= % lim

Well, you could rewrite the servlet in Clojure... right?
Aside from that, I don't think so. Ring works on a much lower level of

You can use 'reduce':
(reduce nth m [2 2 1])
;; or, for the general case
(reduce #(%1 %2) m [2 2 1])
