Here comes... Fortress! Introducing Sun's new programming language

Last week Sun has released its brand-new language, Fortress, to the open-source community.
Fortress is a language designed for high-performance scientific computing, and Sun intends it to replace Fortran.
The language features mathematical notation, transactional memory, value types, operator overloading and measure units. What’s been released so far is an interpreter for a subset of the language running on top of the JVM. A compiler is planned in the future, but I don’t know whether it’ll run on the JVM. But if it does, it can open new horizons for Java game programmers, since a large part of game programming is really scientific computation. Plus, the language has some features long awaited by this community, like value types.
