Stalin (STAtic Language ImplementatioN) is an aggressive optimizing batch whole-program Scheme compiler written by Jeffrey Mark Siskind. It uses advanced flow analysis and type inference and a variety of other optimization techniques to produce code (using C as an intermediate language) that is extremely fast, particularly for numerical code. In a number of tests it has outperformed hand-written C, sometimes by a considerable margin. Stalin is intended for production use in generating an optimized executable.
