Re: redefining multimethods at the repl

Brian, I share your pain. A standardized contrib solution for this would be welcomed. Are there other things like this that cause people to "restart REPL" unnecessarily? I would like to identify the whole list of such things and kill them. Stu > Thanks. I think I'll write my own `defgeneric`

Re: Question about sets

My 2c: 1. Simplicity is partially about having orthogonal primitives. A duplicate-removing collection factory cannot be sensibly used to implement a throw-on-duplicates collection factory, nor vice versa, so both seem equally primitive to me. 2. Given that both flavors are useful, they should

Re: code as data vs. code injection vulnerability

laziness. (1) Using Clojure as a print/read format does not tie your clients to Clojure. Readers exist in many languages, and are easy to implement. (2) XML, despite its baroqueness, is extensible. So is Clojure data. This is a big advantage, and many approaches lack it. Cheers, Stu Stuart
