After discussing with a couple of folks in IRC (big thank you to hyPiRion for
his help), I opened a ticket to address this bug here:
http://dev.clojure.org/jira/browse/CLJ-1181
Long story short, ((formatter-out ~#(~;~@{~w~^ ~_~}~;)~:) nlis) expects
nlis to be a sequence, but in the case of (^:once fn* [x] x) it is a symbol.
Thanks,

Could anyone help me understand why the following code is breaking?

IllegalArgumentException Don't know how to create ISeq from:
clojure.lang.Symbol clojure.lang.RT.seqFrom (RT.java:505)
#(
The #( is not a typo. It starts to print and then fails. Looking at the
code, it looks like there's an issue here:
(defn- pprint-anon-func [alis]
(let [args (second alis)
nlis (first (rest (rest alis)))]
(if (vector? args)
(binding [*symbol-map* (if (= 1 (count args))
{(first args) %}
(into {}
(map
#(vector %1 (str \% %2))
args
(range 1 (inc (count args))]
((formatter-out ~#(~;~@{~w~^ ~_~}~;)~:) nlis))
(pprint-simple-code-list alis
I squinted at it for a bit, but I'm not sure what's up. Anyone have any ideas?
Thanks,
