Hi Mark,
set takes a single argument, a coll, and #{} is a literal form that
can have a variable number of args.
To make them equivalent:
(set "aeiou")

#{(seq "aeiou")}

Here is some code, my question relates to '(not (nil?...':
(if (not (nil? (regex-search-keyword (regex-get-text) line)))
(add-select-style styles-vec all-bold)
(add-select-style styles-vec light)))
Could I have done the following or is (not (nil? ... a better
approach.
OK, I understand better now, I think.
Did you experience the problems you have exposed ? Or is it an anticipation
of problems ?
If so, can you expose the tests data, so that one can also experiment with
them ?

Konrad, the extra memory allocation is often the difference between
something fitting inside a cache line on a CPU and hitting main ram.
Last time I looked, I believe the difference is a factor of
Ah, exactly what I was looking for, thanks.

Are all of these considered "reader macros"?

Is it correct that these are not considered "reader macros"?

Clojure supports functions with multiple arities (http://clojure.org/
functional_programming).
Assuming you don't actually care if you call the function with a
vector, you can do something like this:
(defn sum
([] 0)
([acc & r]
(if (nil? r)
acc
(recur (+ acc (first r)) (re

Below are two operations that print (1 2 3 4). How can I do something
similar to print ("1 2 3" 4) to standard out?
(println '("1 2 3" 4))
-> (1 2 3 4)
(def x "1 2 3")
(println `(~x 4))
-> (1 2 3 4)

Yes, exactly :) Returning nil for no-arg
I type this expression in the REPL (trunk 1228):
user=> (let [s (.keySet {:a 1})] [(set? s) (ifn? s)])
[false false]
But I expected it to return [true true].
Is this an oversight, or is there a good reason for this behavior?

Hi Wubble,
Looking at the code you have above I thought I might point out that
rather than create an anonymous function inside of sum and then call
it immediately after finishing its description, you could just use the
loop/recur construct which is much more idiomatic clojure code. If you
decide

You rece
tree-seq assumes the root is a branch:

([1 2 3] 1 2 3) ; I expected ([1 2 3])
Is this a bug?

He added combinations to lazy-seqs.
I think it's quite cool that simply removing the "when" accomplishes
this.
