ConcurrentProgramming

• Clojure
  • Clojure is a dynamic programming language that targets the Java Virtual Machine.
  • Clojure is a dialect of Lisp, and shares with Lisp the code-as-data philosophy and a powerful macro system. Clojure is predominantly a functional programming language, and features a rich set of immutable, persistent data structures.

Clojure is currently fairly hype-free because there's few reasons outside of the language itself to promote it. It has no marketing people, or large corporations with a vested interest in people using it.[1]

• Yegge, Clojure, Arc, and Lolita: or Days of Future Past

Yes, mostly-functional languages with software transactional memory is the big new trend. Many new languages are being created based on this, and Rich was far-seeing to do it in Clojure. Yes, it’s primarily because we’ll all be writing more concurrent software to take advantage of all the cores. DanielWeinreb

  • Clojure could be to Concurrency-Oriented Programming what Java was to OOP
    • most Java programs are so rife with concurrency bugs that they work only 'by accident'
    • Distributed concurrent applications in Clojure?

• trampoline
  • -> TrampolineStyle
  • TCO -> TailCallOptimization
  • http://lambda-the-ultimate.org/node/3106
• not ObjectOriented
  • use maps where you'd usually use objects
  • Rifle-Oriented Programming with Clojure
    • Any comparison of hot JVM languages is likely to note that "Clojure is not object-oriented." This is true, but it may lead you to the wrong conclusions. It’s a little like saying that a rifle is not arrow-oriented.
• lazy sequences (ClojureSequences)
• consider maps as functions of their keys, and indizes, and sets
• let-bound variables are immutable
• ClojureMacros

Clojure Sucks!

• http://jng.imagine27.com/articles/2009-08-19-011225_clojure_the_false_lisp.html
  • Clojure is not worthy of the Lisp name. It is the antithesis of the Lisp machine in every way. It has little regard for the intellectual rigor and cohesiveness of Lisp.
  • Clojure has inherited many of Java's idioms and problems. Clojure is not only built on top of the JVM. It is also built on the Java language.
