What programming language are you currently learning?
dkarl: I'm learning Scala for the following three reasons (in increasing order of importance.)  These just reflect my current needs, not a prescription for other people, and all three revolve around my need to add a practical language to my repertoire to reduce my usage of C++ and Java.3.  I decided to learn a language I could use on the Java platform using Java APIs, rather than on the _nix C platform using C APIs.  Partly this is a matter of wanting to escape C's shortcomings; partly it's because I have my eye on a couple of upcoming projects at my company for which the Java libraries will be extremely helpful.2.  I want to learn a language that will allow me to use functional idioms and help me learn a more functional style, yet allow me to get the job done even when my functional-fu falls short.  I don't want to learn a language that expands my mind but then becomes a fond memory.  I hope that for many years to come Scala will be the first language I reach for when I need to get something done on the Java platform.1.  I want to master a modern yet practical language with a strong static type system.  I don't do much programming that calls for a dynamic language, and I'm pretty satisfied with Python.  I write a lot of code in C++; C++ and Java are the only statically typed languages that I have really mastered, and I'm dissatisfied with both of them.Runners-up:Clojure:  not statically typed.  Maybe my next language after Scala -- I really enjoyed using Common Lisp but hated the library situation.O'Caml:  great for the _nix C platform, but not for Java.  Also possibly too pure to be a "go-to" language (heh.)
