Here's my take:

(apply str (map (fn [prev curr]
(or (and (= prev \space) (Character/toUpperCase curr)) curr))
(cons \space s) s)))

The second point is somewhat less significant but it does have a
point: With 1-based you need to write (<= i n) instead of (< i n). It
seems that programmers prefer to write less, hence making 0-based
indexing more popular.

the context pattern indifferent of the order of the observers. My
experience shows that observers ordering issues are more complicated
to solve than infinite loops among observers.

Konrad,
Your installation is probably fine. The problem lies in the
FileNameExtensionFilter class. It was only introduced in Java6.
Therefore, despite the fact
that you now have binaries that are compatible with your JVM, the
program does not run. I'll try to fix this soon. I'll post a message

Dan, Marko,
I wonder whether you have the time to do a little experiment. The L&F
is set at line 182 of net/sourceforge/waterfront/ide/ui.clj. Could you
please try to see which L&F works on your machine or, otherwise,
understand why an exception is thrown there?
Thanks,

This is the L&F that Waterfront is usin

Some of the reaction for Waterfront was related to the Application
Context Pattern (ACP) - The pattern that allows most of Waterfront's
code to be purely functional. I'll try to explain the basics in this
post. Let me start with the motivation: the reason why FP is at odds
with GUI code.

For those of you who encountered issues/bugs with Waterfront, you not
submit reports at:

My intention is to get Waterfront into contrib in the near future.
Till then, Waterfront will stay on sf.net.

and so far I didn't encounter any
bugs.
I guess that over the course of the next few days, as people start
using this version,
a few issues may come up. I'd be glad to fix these.
I also took Mike's suggestion, Waterfromt's main window is now using
a side-by-side layout.

All, thanks so much for the feedback.
I am working on adapting Waterfront to the Clojure's latest snapshot.
Will let you know when this process is complete. Till then it can be
tried with Clojure's previous version (Dec.17).

I want to be able to read and write a clojure object, which contains

The structure looks something like this: { :s "my-string" :f (fn[x]

Reading is easy: (load-file ...) works fine. The tricky part is
writing it back to the file. (pr ...) gives something like
No doubts this is very elegant. However, I think that the underyling

there's a map which is essentially a RAM. Each instruction writes to
this RAM (alters the mappings in the map).
It seems that a stack-machine exhibits a more functional nature: an
