Ah, I found out that java bytecode can't contain data literals so the compiler has to emit a constructor instead. Also, since the jvm doesn't gc classes there might be confusing memory leaks if you could embed a closure in evaluated code. On 9 August 2013 09:13, Christophe Grand wrote: > You are

Obviously I've encountered the advice "no macros unless you know you need them" before. And I even sort of know the syntax and what they do. I don't think that's my problem. I think I've lived a life without macros. I mean, clearly dynamic-functional and even OOP styles are perfectly capable of bu

Re: Lisp newbie seeks (macro?) wisdom - instrumentation and app metadata

For a pretty decent cover of when and how to use macros, On Lisp[1] is a pretty good book. It's written mainly for Common Lisp but most of it translates to Clojure well enough. I find that for common code, writing macros isn't so useful as most of the goods ones are already part of clojure.core

The difficulty with On Lisp when applied to Clojure is that the specific macros On Lisp demonstrates either depend on state, which Clojure avoids, or are already present in Clojure core. (if-let is a big one in my book.) Some of them also run into conflicts with Clojure implicit gensyming. I do
