All the above suggestions are good. In addition, I've learned a lot by
doing the problems at 4clojure.com.
BUT after you solve a problem, the real learning starts. You then get
access to other people's solutions. (You get to choose whose answers get

Hi--
The code in question is a solution to http://www.4clojure.com/problem/58
(write a function that does function composition, without using 'comp').
The solution I'm trying to understand is by amalloy:

(reduce (fn [f g]
#(f (apply g %)))
fs))

@Dru, I feel I'm ahead of you in learning Clojure, but I'm not yet to where
@Colin is. However, I'm close enough that I recognize how accurate and
concise his advice is--in fact, I'm saving it to remind myself!
Also, I just finished reading Functional Programming Patterns in Scala and
Clojure,
solutions, looking at
both the factors of elegance and readability in solutions.
do you have any good projects/solutions recommended?

This is good advice, but I can't parse 1a after the phrase or maybe,
and I'm not sure about 1b. Can you reword them, making it clearer when
you're using a Clojure keyword? I want to be sure I understand what
you're saying--it sounds insightful! Thanks.
