Okay, got it. It looks like you're using agents where I'd been using
atoms. Not sure if there's much of a difference for these use cases...
the one-directional flow of source -> state -> watcher update
notification -> ui change seems to work well with both agents and atoms.

Daniel,
I've just finished reading this series and thought it was superb. The Emacs
chapters in particular were a massive help. I'm a complete newbie with
Emacs and the detail here was pitched just perfectly. It got me exactly
what I needed to start to become productive very quickly.

I've read Daniel's series 'Clojure for the Brave and True' and I highly
recommend it as a resource both for the excellent content/philosophy and
humour :)
It personally made the Clojure introductory learning experience a very
enjoyable one. Thanks Daniel.

Seqs in Clojure are very much like iterators in other languages. They're an
abstraction for navigating a sequential data structure.
Also because values in Clojure are immutable, you rarely, if at all,
encounter situations where those objects need to be copied. Why would you,
when you can just refe
Great work!
Regarding the screencast: I would be very interested to hear about your Clojure
development setup with Vim, especially the plugins and configuration you are
using.
I see you are using some sort of split view with Vim on top and a REPL at the
bottom. Is that GNU screen split in two
Nice James, I like it :)

Can a seq be thought of as a kind of a list of pointers to the original
vector elements then? If so, then does an operation on a vector, (e.g.
reverse), cause clojure to internally generate a seq of pointers to the
original vector elements? In other words seqs seem to provide a layer of

Interesting alternatives. (vec) makes a vector out of a collection, so this
is meant to be faster than (apply vector)? Also how does (into []) differ
from (vec) in terms of what it does and its performance?

Thanks both for your answers.
@Ben, that seems to do it. I was trying to make it a bit "nicer" but failed

The result of that is

Sorry, I spoke without seeing that you were aware of partition-by. Here's
one that isn't vectorized.
(def v ["foo" 1 "bar" 10 20 "clown" 5])

Hi all,
I have a vector which contains an unknown number of repetitions of the
following pattern:
String, followed by 1 or more integers
For example:
String
Integer
String
Integer
Integer
String
Integer
Integer

String

What I am trying to do is to create a vector of pairs which

What is the proper use/require/refer entry to export foo's bar as mine's
bar without defining a new public bar in mine?
