As usual, Meikel has the right answer. But I didn't quite get it at
first.
It looks like syntax-quote generates cons's, not lists:
user> (type (nth `(handler-case :type (println "test") (~'handle foo))
3))
clojure.lang.Cons
Your macroexpand-1 example worked because the reader doesn't
distinguish between cons's and lists.
Because handler-case is expecting a list and syntax-quote won't
generate one, you'll have to write your macro like this:
(defmacro test-failure
[& forms]
`(handler-case :type
~@forms
~(list 'handle :error/error
'(println "error happened"))))
Finally, a shameless plug: you could have used the cdt, or debug-repl
to set a break around line 92 and figure it out yourself. That's what
I did.
