I love the idea.
A gotchas section of some sort could be useful. For instance, a detail
about `case` to consider mentioning is that Java Constants don't work as
tests.
ryans-mbp:~% cat test.clj
(let [incoming-character Character/LINE_SEPARATOR]
(println "case w/ constant"
(case incoming-character
Character/LINE_SEPARATOR :line-separator
:unknown))
(println "case w/ int "
(case incoming-character
13 :line-separator
:unknown)))
ryans-mbp:~% java -jar $CLOJURE test.clj
case w/ constant :unknown
case w/ int :line-separator
I think I understand why this doesn't work but it feels like it should
work. And without prior knowledge, I don't think I would assume that
constants don't work.
