Performance of thread-local binding

If I understand Clojure's dynamic vars correctly, in a context where some var *bar* is already thread-bound, the following code: (binding [*bar* new-val] (foo)) is semantically equivalent to: (let [old-val *bar*] (set! *bar* new-val) (try (foo) (finally (set! *bar* ol

Re: lein run and standard input (*in*) with read-line

Hi Phil, thanks, lein trampoline run seems to get around the problem. BTW, spotted a minor error in the .lein/bin/swank-clojure script. The CLASSPATH setting at the top of the script appears to have a hard coded path instead of one based on $HOME. For example, after installing the swank plugi

clojurescript collection vs sequential problem

I noticed in clojurescript/src/clj/cljs/closure.clj that the function build calls -compile and binds the return value to compiled. compiled is then checked if it is a collection, and if not, wraps it in a []. The problem is sometimes compiled is a hash-map, and this counts as a collection. In my

Re: checking if a method is defined

Also keep in mind, that in (.something obj), the compiler doesn't see a call to .method, but the whole thing is desugared into a call to the dot form: (. obj something). Since . is a special form, it is always defined. So when trying to analyze a call to the dot special form, keep in mind that the

Re: (.containsKey {:one 1} :one) throws Exception

Looks like the type inferencer inserts a cast to PersistentHashMap, where it should only cast to clojure.lang.Associative (the interface on which .containsKey is defined). Also, the type inferencer picks up the wrong type from the literal, but that wouldn't matter, if it would always cast to the mo
