A plan for learning clojure

I had printed out the list of functions and macros in the Clojure API page, and it filled out two A4 pages. Where to start though? I walked the entire clojure and clojure contrib directory and counted the number of function calls. Here are the top stats.

sym	count	len
clojure.core/list	3872	17
quote	2749	5
defn	1757	4
clojure.core/seq	1481	16
clojure.core/concat	1480	19
=	1074	1
let	1042	3
is	885	2
.	836	1
if	826	2
defmethod	431	9
def	407	3
complex	377	7
defn-	376	5
fn	356	2
first	346	5
defmacro	298	8
clojure.core/apply	264	18
deftest	257	7
str	252	3
when	244	4
imaginary	238	9
recur	237	5
apply	229	5
instance?	220	9
nil	217	3
and	214	3
next	208	4
cl-format	206	9
fn*	197	3
ns	194	2
map	193	3
:use	187	4
list	184	4
1	181	1
count	178	5
+	169	1
seq	167	3
reduce	165	6
are	148	3
cons	143	4
println	141	7
or	141	2
not	135	3
loop	133	4
thrown?	127	7
*	127	1
conj	125	4
print	124	5
nth	124	3
-	116	1
doseq	114	5

Now, I have a study-plan.

Incidentally, waterfront IDE is quite nice, particularly because I don’t have to learn Emacs key-bindings. There are some moments when it barfs and prints out hashmaps incorrectly, but I enjoyed working in a REPL environment.
