Just to chime in - my nleiningen prototype has a repl and a compile task,
but is basically just a prototype or proof of concept. It more or less
works (i.e. can download dependencies & compile namespaces), but it's very
rough at this point... Hopefully soon we can put some more work into it.

I'll throw in my own work in progress as a low-footprint target of Clojure:
https://github.com/aaronc/c-in-clj. It's not an attempt to compile Clojure
code to C, but rather a way to write C code efficiently from Clojure that
can be dynamically invoked from Clojure.

I'll share some of my experiences.

Yes, I have been using it in production for about 2 years now.

I have been working on a library for ClojureCLR that actually uses a
Clojure DSL to generate, compile, and load C code live into a running REPL.
It's called c-in-clj (see https://github.com/aaronc/c-in-clj). It works
quite well for me so far, but is still in what I would call Alpha stage.

Whereas you need:
user=> (amap (float-array [1 2 3]) i ret (float i))

You can call extend-protocol several times:
user=> (defprotocol A (foo [a b]))
A
user=> (extend-protocol A (Class/forNam
A watcher fn has 4 parameters: key, reference, old-state, new-state
If you use old-state and new-state rather than the reference, you should
not see your problem.

Haha, I come back to this list after a good few months of not being able to
keep up with the volume to find a rant about paredit - priceless!
Seriously though, these things are all personal and as such clearly get
people's backs up. So for what it's worth, let me throw my thoughts in...

Hey everyone,
I just thought I'd give you a heads up of what I'm currently doing with Clojure

What repl are you using? I think it's doing something weird.
java -cp clojure-1.5.1.jar clojure.main
user=> [do (inc 1)]
2
user> ^{:line 11, :column 20} []
ClassCastException java.lang.Long cannot be cast to java.lang.Integer

I'm not sure if you'll consider this hacky or not.
