Doug Hoyte's book Let Over Lambda (http://letoverlambda.com) has plenty of tips on how to hack closures, including accessing closed- over values. The book uses Common Lisp, but most of it maps easily to Clojure. The relevant chapter on anaphoric macros is not available in the free preview, unfortunately. To summarize in Clojure terms, you make a wrapper macro for fn, called, e.g., pfn. pfn then works exactly like fn, except you may also use it with some predetermined arguments. Those arguments make the closure return closed-over values. -- You received this message because you are subscribed to the Google Groups "Clojure" group.
