• Writing a DSL (Domain Specific Language)
• Writing concurrent code

The languages that seem to come up are:

• Clojure (JVM)
• F# (based on OCaml, Haskell, and ML) (.Net CLR)
• Erlang (JVM)

I’m not particularly interested in DSL (despite my last post on code generators), however as CPUs contain more and more cores, we’ll need a way to safely write multithreaded code.

The Clojure project has an interesting post on its approach on simplifying multithreaded code.

Erlang handles concurrency by only having local variables and providing a way to send messages to and from other threads.

Lastly, MPI is a .Net library for distributed processing where the same program executes multiple times and each instance communicates with each other using message passing which sounds very Erlang-like.
