Patch Review

So it's great to see new ideas popping up like protocols and datatypes, but I've noticed that the list of patches ready to apply to Clojure gets pretty long and doesn't seem to move that fast. I don't mean to complain; I'd much rather have Rich and co. working on exciting new features than spendi

function rebinding and logging

Hey, I'm working on a small to medium sized, hopefully commercial product in clojure. I'll be providing an API to clients, and I'm also going to have to make some performance guarantees about a few of my functions. Because of that (as well as a few other reasons), I'm very interested interested in

Re: prn/read and infinities

I'm thinking this should be handled at the reader level, not the evaluator. Since doubles are normally "understood" at read time, reading these values as symbols and expecting the evaluator to get them right could lead to unexpected behavior. On Tue, Oct 20, 2009 at 11:57 AM, Rich Hickey wrote:

Sounds like the tree is what I need (since the data will be changing quite a bit). As for using a hash-map: wouldn't you need a sorted map to be able to pull out all the keys in a range? And then are the seq functions efficient for this? (I.E. if you drop a number of them to get to the beginnin
