Clojure 1.6 API: clojure.lang.IFn and clojure.api.API

So these APIs are new in 1.6-SNAPSHOT and from what I understand provide an integration api between Java and Clojure-Runtime (symbols and their invocation). Apart from limitations which probably exist, what is the mode of execution for these API-calls ? For example if a tool/IDE starts a (REPL)

it happens with both clojure 1.5.1 and 1.4.0. when intellij tries to compile clojure files, something strange happens. if i remove the option to compile the files (and instead just use clojure.main and run them) there is no problem 2013/6/22 Jim - FooBar(); > On 22/06/13 15:21, Dennis Haupt w

Ah ok - so I may be using it wrong. I am not calling the function itself - I was simply trying to bind local variables in a loop. I have placed the code into gists for easier reading! https://gist.github.com/anonymous/5841405#file-core-clj https://gist.github.com/anonymous/5841420#file-vec-clj

Do you have the stack trace? It's not simple to run the code, but I made a github project so we can look at it easier. https://github.com/gtrak/grad-descent-test When I run (gradient-descent example-grad [0 1] 0.001 0.001) Here's the actual problem: grad-descent.core> (pst *e) StackOverflowError

Re: Best practice for looping

I think the way to understand what's going on is to realize that laziness (coming from map) creates extra thunks, for each iteration, you're creating an extra stack frame to dereference the elements of the lazy seq. (defmacro lazy-seq "Takes a body of expressions that returns an ISeq or nil, and
