Gary Fredericks discusses macros, what they are, how to write good ones, when to use them and when to avoid using them.
Gary Fredericks is a software developer at Groupon in Chicago. He's been using Clojure professionally since 2009, and spends half of his free time trying to write code that visualizes and explains concepts from pure math and computer science.
Clojure/West is the newest conference creation from Alex Miller (aka @puredanger). Alex has been running the Strange Loop conference in St. Louis since 2009, smashing together the worlds of functional and dynamic programming languages, concurrency, distributed systems, web and mobile. Since early 2010, Alex has also been part of a team using Clojure at Revelytix.
