Hi,
Can we add the following to contrib's sql namespace, it simply adds jndi
as a db-spec scheme ( I also raised this as
http://code.google.com/p/clojure-contrib/issues/detail?id=39 , which google
decided to set as a defect and I can't change):
Index: src/clojure/contrib/sql/internal.clj
See also partition-all in clojure.contrib.seq-utils. It isn't as
feature-complete as your version, but is instead a drop-in replacement
for partition that always returns the final part (regardless of
whether or not it's long enough).

From what you say I imagine you have something like a matrix
or table, something with rows and columns that form cells.
And you want to be able to grab the contents of one cell and move
it around to another cell.

Thanks for the feedback. I'm still a bit stuck though since neither my

Thank you Rich for answering, I appreciate your expertise.
It's always best to post a complete example - it makes it easier for

Thanks for the feedback!
I would have liked to call the arrays arrays but java's arrays make
that name less than ideal. If people think a better name for the
library is persistentarray, I'm not opposed to changing (especially
this early in the game).
It shouldn't be a problem to

Hi, the version of repeatedly-while I submitted still takes an argument for
the predicate function, that would be the value of the last generated item
in the list:

The problem (such as it is) with these solutions is that you still need
to do something to attach to a repl. A repl is a requirement for us.

Well the solution in my case was to create a map from visited types to

this map in order to invoke the next visit (http://tinyurl.com/

I would set your *warn-on-reflection* flag of course to see if you're
missing out on any type hinting. Also watch out for math ops that involve
more than 2 arguments:
;; takes ~400ms on my machine
(time (dotimes [x 100]
(* 1 2 3)))
;; takes ~50ms on my machine
(time (dotimes [x 100]
(* 1
Also type hinting your math ops like mad on tight loops helps:
;; ~20ms
(time (dotimes [x 100]
(* (float 1.0) (* (float 2.0) (float 3.0)
;; ~65ms
(time (dotimes [x 100]
(* 1.0 (* 2.0 3.0
Another 3x increase.

The java version is much faster even with much more work to do, which

One comment, although this has no effect on performance: you don't
need to use the static class fields as functions. That is, you can
write Math/PI and Short/MAX_VALUE instead of (Math/PI) and (Short/
MAX_VALUE).
