General Development InfoWorld's Peter Wayner reports on once niche programming languages gaining mind share among enterprise developers for their unique abilities to provide solutions to increasingly common problems. From Python to R to Erlang, each is being increasingly viewed as an essential tool for prototyping on the Web, hacking big data sets, providing quick predictive modeling, powering NoSQL experiments, and unlocking the massive parallelism of today's GPUs.

RE[2]: Dawnfall of OO?

I never really understood what "everything is an object" means. In fact, I share with Stepanov the opinion that it means nothing at all.
I can understand, however, "everything must be declared inside the scope of a class, and used through instanced objects". And I don't like it. It's unproductive, and push people to produce inefficient, long and brittle code.

If I want (for example) to implement an algorithm which takes a raw data set and produces a quantized result, why should I abstract a class of it? And why should it work only on a few datatypes/classes, which must make explicit reference to it though inheritance?

I would like to see programming languages advancing in that kind of tasks, in order to produce generic code that molds itself to different data instead of the class/inheritance mess.
But please not in the path of the C++ templates; I mean solutions that can be read/used/compiled by humans.

I view "everything is an object" to mean that everything (or at least most things) is first-class: functions, methods, classes, etc. can all be passed around, and thus used much as "normal" objects. Smalltalk/ruby especially exemplify this, Java not so much (no first-class functions, etc. only reflection hacks)

I agree that not everything needs to be done through instanced objects, etc. However, it's nice to have OOP or something similar (haskell typeclass, etc.) when you do want it.

Inheritance has its ugly parts, especially in Java, but I don't view it as fundamental to OOP (or even classes, really). As Alan Kay said, it's all about the messages; OOP allows an object to be used elegantly without regards to its actual implementation.
