Yet another approach that might work for you, depending on your
requirements, is to use a lazy sequence to access your data. I did that
for a load of Twitter data that would have been too large to hold in memory
at any one time.
Here's the relevant bit (I think), copied and pasted:

Here is the quick clojure sample:
user= (def p1 `(or a b))
#'user/p1
user= (def p2 '(or a b))
#'user/p2
user= (= (first p1) 'or)
false
user= (= (first p2) 'or)
true
At the same time this seems unique to clojure as the clisp behavior differs:
[1] (setf p1 `(or a b))
(OR A B)
[2] (setf p2 '(or a

Hi,
for hygienic reasons. ` qualifies symbols, while ' does not. So `or might
result in clojure.core/or, while 'or is always or. This is important. Consider
the following example.
(ns foo.bar)
(defmacro foo-or
[ body]
`(or ~@body))
(ns frob.nicate
(:refer-clojure :exclude [or])
(:use
Oh, I see it. Well, it complicates the matters but at least it is not a bug
:)

In fact it makes things less complicated. You rarely want a quoted symbol in
Clojure. Most of the time you'd use a keyword in such cases.
Kind regards

While we're at it, I'd also add a one-sentence introduction about what

As pointed out by Chouser and others the direct invocation does introduce a
bit of static-ness to ClojureScript.
In particular switching a top level definition from a fn to an object
(which implements IFn) can cause problems. The compiler now issues warnings
if this happens.

Hello,
I'm working on porting underscore.js to clojurescript (at least the parts
that aren't made redundant by clojurescript already). Mostly it's pretty
straightforward, but for some of the trickier functions I'm having trouble
finding an idiomatic translation.

It does seem like you need to use native js data structures if you want
speed. Makes sense, and it's not a big deal beyond the psychic injuries
caused by going mutable. I've had to switch from vectors/maps to
arrays/objects a few times due to performance.

IME, it's almost never useful to perform equality tests on floating
point values. Generally you want to know if they're near enough to one
another without necessarily being exactly equal. For that something
like (defn f= [f1 f2 threshold] ( (Math/abs (- f1 f2)) threshold)) is
probably the sort of
