Call me old-fashioned, but this seems like not the best way to approach choosing a language. It should be chosen pragmatically, by considering what works best for the task at hand, not because of arbitrarily set rules, and never because a language is new and exciting.

Re: Presentation about Clojure

For me the most practical benefit of Clojure is how easy it makes combining, transforming, and processing data from various sources. Just as SQL is better for querying a relational database than writing a load of imperative for-loops; Clojure's functional transformations of immutable data are far m

David, I personally have no plans to port tools.analyzer.jvm to a tools.analyzer.clr, not for disinterest but simply because I don't know anything about the .NET platform nor about clojureCLR. That said, it shouldn't be hard to port it at all, the main file to port would be https://github.com/cl
