I updated the gears demo port to use the new Java interop syntax. It
runs, but it would be nice if somebody would give it a good looking at
to make sure I didn't do anything truly stupid.

Many of the provided functions take arguments named "coll" or "seq".
Is the choice meant to indicate something significant about what can
be passed? As far as I know, every collection can be treated as a
sequence. Maybe the opposite isn't true.

(defn ns-var-metas [ns-name]

One thing I'll mention is that most of the libraries and user code is

currently maintaining copies of the files in the old locations, but I

once everyone has switched.

I suspect that the "obvious way" to concatenate vectors, i.e., (into

--~--~-~--~~~
I would expect something like this to work:
(String. (into-array [\a \b \c]))
would yield "abc",
but it gives me an error.
It seems very natural to turn a string into a Clojure collection to do
various manipulations, but then how do you turn a collection of
characters back into a string?
