Oh, does that work in 1.3? Because (new (Class/forName "user.Foo"))
was the first thing I tried (under 1.2) and it doesn't work. Perhaps
unsurprisingly given that new is a special form.

You can bind functions inside a let, which can help if you're just
trying to make code less nested. The thread-first and thread-last
macros help here too. But if you're looking for the equivalent of the
"private" keyword (sort of) check out defn-. Note the dash at the
end.

Yeah, that code was cut and pasted from some older work I did. It was
removed when I started using prxml.
As I mentioned previously, I'm going to see if I can get time this
week to set it up to go through clojure.contrib.prxml. If I don't run
into any issues, that will remove the dependency on the javax stuff
I'm importing. It will have the additional benefit of cutting the code

You should double-check: I had the same problem, and it was related to
not having an up-to-date implementation of Clojure. Be aware that you
probably need to run "ant clean jar" on the Clojure sources after
getting them from SVN.

I must be missing something. Even if you have to make every

One way I could think of to do this would be to build a map with each
unique item as a key and the count as its value. Then it would be
trivial to pull out the keys with the count as a specified value. I

If you're cool with passing a map instead of plain parameters, you
