Comments on: Anonymous function literals and syntax-quote don’t work well together http://onclojure.com/2010/03/01/anonymous-function-literals-and-syntax-quote-dont-work-well-together/ A blog about everything Clojure Thu, 09 May 2013 14:29:18 +0000 hourly 1 http://wordpress.com/ By: khinsen http://onclojure.com/2010/03/01/anonymous-function-literals-and-syntax-quote-dont-work-well-together/#comment-77 Mon, 01 Mar 2010 15:12:38 +0000 http://onclojure.com/?p=99#comment-77 When I discovered this problem, my first idea was to find a fix and propose it for inclusion in Clojure. But I didn’t find any, so I wrote this post as a kind of public warning.

However, Rich Hickey, Clojure’s creator, did find a fix, and applied it immediately. If you work with the master branch of Clojure’s github repository and pull in today’s changes, the code in the example will work just fine. This may be the quickest fix of something never reported as a bug!

So what’s the trick? Clojure now appends # to the function argument symbols in expanded function literals. Syntax-quote treats such symbols specially, replacing them by guaranteed-to-be-unique generated symbols, which moreover are not namespace-qualified. Problem solved.
