Of course–it's good that Clojure does that. :) Along with the fact

Thanks for the replies. Mr. Brandmeyer's solution is exactly what I
needed; I don't really want to change rep+'s return value from a
vector, which would sort of break backwards compatibility.

I use Clojure's classes a lot in my multimethods. Is there any way to
abbreviate them; that is, is there a method to refer to
clojure.lang.APersistentList as APersistentList? I've tried (use
'clojure.lang) and (require ['clojure.lang :as 'c]), but neither seem
to work.

Wonderful. Thanks for the answers.

clojure.xml/parse returns a PersistentStructMap. Is there a way to
refer to its struct template? I wish to create accessors for its keys,
such as :tag, :attrs, and :content, with the accessor function for
speed.

I'm pleased to announce FnParse, a monadic functional parsing library
for Clojure, half a year in the making. I started on FnParse in
December as my first Clojure project, and now it has matured to
something that I believe is very and immediately useful. Currently,

In clojure.contrib.def, I'd love to have a defmemo macro that acts
just like defn, only with memoize. I'm planning to change a lot of
functions to use memoize, and I'm not looking forward to changing
nice, clean defns with docstrings to (def {:doc docstring} function
(memoize (fn ...)))s. Would th
Excellent. This will be a lifesaver—thanks a lot.

Awesome, thanks for the quick answer. I think that it'd be a useful
thing to add to seq-utils or something. :)

I've just discovered the clojure.templates library [1], and I'm
wondering what's the difference between its function and that of
regular functions:
(apply-template '[x] '(+ x x) '[2])
((fn [x] (+ x x)) 2)
