Clojure 1.5 new features

With Clojure 1.5 RC1 out, we'd like to spend some time looking at the new features in Clojure 1.5 (and possibly 1.4 features we missed). Rather than a single large presentation, we'd like to crowdsource the topics lightning talk style. That means we'd like everyone to take a look at the new list of features and (if you feel comfortable) pick one to explain to the group. This could be as simple a quick 2 minute dramatic reading of the release notes text or a 10-minute demo of the feature. You do not need to be an expert in the topic, you just need to be willing to spend a few minutes looking over the feature.

Current speakers:

threading macros - Paul Bostrom marker protocols - Sam Griffith metadata - Sam Griffith reducers - Norman Richards print-table - Norman Richards reader literals - (any volunteers?)

Possible topics:

1.5 Release notes: https://github.com/clojure/clojure/blob/master/changes.md

2.1 Reducers 2.2 Reader Literals improved 2.3 clojure.core/set-agent-send-executor!, set-agent-send-off-executor!, and send-via 2.4 New threading macros 2.5 Column metadata captured by reader 2.6 gen-class improvements 2.7 Support added for marker protocols 2.8 clojure.pprint/print-table output compatible with Emacs Org mode 2.9 clojure.string/replace and replace-first handle special characters more predictably 2.10 Set and map constructor functions allow duplicates 2.11 More functions preserve metadata 1.4 release notes, if someone wants to jump back in time: https://github.com/clojure/clojure/blob/8b52c00fa57563d5e7757c09cdd6379edd3c62ca/changes.md

If you are interested a topic, please add a comment to the meetup and we'll add you to the list. No topic/talk is too small, (feel free to grab more than one) and no experience with the feature is necessary.

Side topic, time permitting:

Norman will talk about the Cloudbees clickstart group project project and our github.

Thanks again to Capital Factory for giving us a space to meet at!
