Another interesting approach would be real compiler support for promises so we can get something closer to Clojure JVM semantics. This would require someone to get a bit more serious about the CLJS AST and related infrastructure for pluggable passes. David On Mon, Nov 26, 2012 at 6:51 PM, Frank

seq?, sequential? and coll? are the predicates for ISeq, Sequential and IPersistentCollection, respectively. Sequential is just a marker interface which doesn't promise anything but a defined order of elements. Since ISeq already is a seq and IPersistentCollection derives from Sequable, both will

Encoding Keywords as Strings is a performance optimization in clojurescript. js/String is in fact extended to IFn to make it work https://github.com/clojure/clojurescript/blob/master/src/cljs/cljs/core.cljs#L1795 I don't think it is an immutable design choice, but a replacement with interned Keywo

Using a dynamic number of lvars in core.logic.

Using core.logic, I sometimes have the need to create a variable number of fresh lvars. For example, I want to create all possible combinations of "n" numbers between "min" and "max". Currently the only way I found how to do this was building the expression and evalling it: (defn generate-symb
