|| Logic programming languages have been around for more than twenty years. Despite the expected advantages of a very high level programming language based upon well developed theories of logic over conventional programming languages (such as C, C++, Pascal and Ada) they have not had significant impact on the computer industry.
Mercury is a new logic/functional programming language, which combines the clarity and expressiveness of declarative programming with advanced static analysis and error detection features. Its highly optimized execution algorithm delivers efficiency far in excess of existing logic programming systems, and close to conventional programming systems. Mercury addresses the problems of large-scale program development, allowing modularity, separate compilation, and numerous optimization/time trade-offs.
