Vectors are designed for contiguous/sequential data. The case below requires
removing elements at arbitrary (keyed) locations in a collection.
Idiomatically, a map is better suited to the job. With a vector you'll be left
reassembling your key.
It's worth noting that calling assoc on a vector

clojure ideas and instead of java use '.' for easy access to C/C++

How should I say it... It just didn't look symmetrical to me.
So, basically, there is a difference between functions returning
sequences - depending on if they are lazy or eager. Hmm...
user= (reverse [])
nil
user= (if (reverse []) true false)
false
user= (if (seq (reverse [])) true false)
If I've been following things correct:
rest _used_ to force the seq, it does no longer.
next forces the seq
In my own mind i'm thinking next to mean (return the seq with the next value
computed), rest now means just give me the uncomputed remaining values of
the seq.

Hi,
I believe the following is a bug in clojure.contrib.lazy-xm:
user= (use 'clojure.contrib.lazy-xml)
nil
user= (emit { :tag :a, :attrs { :b bloody apostrophe's :-) }})
?xml version='1.0' encoding='UTF-8'?
a b='bloody apostrophe's :-)'/
nil
The XML is broken, because the embedded apostrophe
clojure.xml/emit adds newlines before and after the content of an
element, and as far as I can see there is no way to suppress it:
user= (use 'clojure.xml)
nil
user= (emit {:tag :a, :content [b]})
?xml version='1.0' encoding='UTF-8'?
a
b
/a
nil
As whitespace within XML elements is significant,

The Common Lisp and Scheme books suggested are great, of course,
particularly _On Lisp_. However, I think learning CL or Scheme is an
awfully roundabout way to learn Clojure.
I think we should really be pushing the Pragmatic book. It is good and gets
the user to Clojure in a straight line.

That's really nifty, Phil! I'll have to check it out.

Seeing this topic comes up a bit, I've taken the liberty of compiling

Do you think it's worthwhile to add `not-empty?' in the core?
It just feels more natural to go:
(when (not-empty? (filter even? [1 2]))
...)
over
(when (seq (filter ..)) ..)
What do you think?

In the definition of dorun:

When lazy sequences are produced via functions that have side
effects, any effects other than those needed to produce the first
element in the seq do not occur until the seq is consumed. dorun can
be used to force any effects. Walks through the
