This is for all those polyglot users - how do you find Clojure has changed
the shape of your application? By shape I mean the code artifacts. For
example, I find in Java I tend to have many packages (in some dead-end
attempt at hinting at modular encapsulation) and many little classes and

Hi All,
One of my first posts to Clojure mailing list. I had an idea around SCMs
and Clojure. I'd basically like to put the idea out there and get some

Hi BG,
Basically looking to learn and explore. From the top of my head, maybe
couple of hours of solving a few project euler problems, as pairs. The
solutions by each pair can then be presented and discussed in the entire
group.
Or maybe a 30 mins talk modeled around lightning talks.

Thanks for your reply. I agree that you need a persistence layer and a VCS

It's a nice program, that I know how to operate.

Okay, first, I create an atom that holds a set:

Because it works on nearly all
your apply will end up doing sometihng like this:

since apply takes @visitors as a collection and passes each item as an

In other words, apply essentially unpacks the collection and passes
the items as individual

I think you should not explain def as a function, as that is not a

You could just explain how it behaves without mentioning special forms

Design question: I made a new branch of the code where you extend the Is-A

I have a hard time understanding why there is a need to retry when doing
swap! on an atom. Why does not Clojure just lock the atom up-front and do
the update? I have this question because I don't see any benefit of the

if you do it as a lock, then readers must block writers (think it
through). Clojure's reference types + immutable datastructures and the
views on perception that underlay them are strongly opposed to readers
interfering with writers.

I don't think so. After some practice you can read patches as if they
were finest prose. ;-)
Yea, for prose they work. I believe that. But I'm paid for writing code :)
There are already special-purpose, format-dependent diff/patch tools,
e.g., XMLdiff, various binary diff/patch tools, and
Why is it so? Does not the reader just get a snapshot copy of the atom state
and does not care who writes to the original atom? If a lock is needed, it
is only needed for a very short commit time (cannot read when a writer is
committing), but not during the whole swap! function. That still
