descubes writes "A recent article asked about improvements in programming. Concept programming is a very simple idea to improve programming: program code should reflect application-domain concepts. What is amazing is not the idea itself, but how often we don't apply it, and how much existing tools and techniques can get in the way without us even realizing it. To be able to represent all concepts equally well, we need tools that don't force a particular, restricted vocabulary on us. The Mozart project is a Free Software project to implement concept-programming development tools. It includes the Coda universal intermediate language, the Melody persistent program representation, the Moka Java-to-Java extensible compiler, and a fairly advanced front-end for a new programming language called XL. In the long run, Mozart can give the Free Software community a foundation for something as powerful as Charles Simonyi's Intentional Programming."
