Looking at how the #^ macro is used in core.clj confuses me even more.

Following James's description, I would image constantly's
implementation to look something like the following.
(defn constantly [value] #(identity value))
If you haven't seen the # macro before, the form below is equivalent.

Meikel, found a few more things that might need fixing.
1) In the preview window it says "Use \p to close this buffer!", but I
have m LocalLeader mapped to ",". I'm guessing maybe you hardcoded
this by accident?
2) When doing a macroexpand (me or m1), the cursor is moved into the
REPL buffer.
Could Clojure have something similar to CL's 'defconstant'?

Rich, I think it really depends on what *YOU* want Clojure to be. If
you want to take a Haskell like approach and "avoid success at all

To me, it seems like you have two orthogonal pieces of data, and a

I was able to make this go away by adding a method to Numbers.java. I
have a use case where I'm calling bit-and with two longs tens of

Ole,
Glad you liked my posts on Riak. I took a quick glance at your code
and it's amazing how much Clojure I've forgotten over the last year.
I need to read my Joy of Clojure :)
If you're looking for Erlang/OTP in Clojure land than I think an
easier path might be to look at Erjang [1]. AFAICT,
I'm also interested. I just started to go to beehive occasionally and
I was recently discussing with someone how it would be nice to have a
FP group. I live in Federal Hill.
