Hi,
I'm trying to write a function that calculates the length of a list:
(defn list-length [col]
(if col
(+ 1 (list-length(rest col)))
0))
(list-length '(Java, Clojure, Scala))
Upon running it in the REPL, I got the error:

One benefit of having a REPL: it makes regular expressions usable. So easy
to test and tweak your RE compared to the traditional compile/test/debug
cycle! I never even bothered with the java.util.regex package before Clojure

Danny, could you maybe hack up a possible very simple example of what
you mean?

I can not simply store a copy of the Karl person in Tinas :friends
slot,
because when Karl gets one year older, then I don‘t want to go through

How can we handle this situation?
Is it possible to implement a function “deep-deref” which works
as blindingly fast as deref does?
I find this very important, and this is of great practical relevance
for me. Please share your ideas
Hi André,
I had a similar issue with

Hello,
I've just started learning Clojure, so I'm trying to figure out the
correct way of doing things. I've been trying to create and 'modify' a
large vector for an online programming exercise, but I'm running into
some performance issues.
Any general tips would be
of the vector on every iteration: I suspect that may
involve a traversal of the vector every time it's called.
Cheers,

Perl and Ruby do something similar with regular expressions, where the
character following 'm' or 's' becomes the delimiter for that
expression, making 'm/\/some\/path/' identical to 'm!/some/path!'. The
delimeter can be 'smart' as well, where the closing delimiter is
dependent upon the opening
