1. An extremely aggressive Scheme compiler. stalin is an aggressive self-hosting Scheme compiler, designed to generate resource efficient stand-alone executables with very high computational performance. It is a batch mode compiler like gcc, not an interpreter, and is designed to be used only after your code has stabilized. It places a few limitations on the content of the source code. For example, you may not not LOAD or EVAL new expressions or procedure definitions at runtime, but in exchange, it is able to perform various global analyses which may allow it to transparently map Scheme types to C types and to use native C arithmetic operations on a per-expression basis, whenever such operations are proven safe. Further stalin can often reduce or eliminate run-time type checking and dispatching, and omit garbage collection for data of limited scope or accessability, while omitting unreachable data altogether. stalin also has a foreign procedure interface to both Xlib and OpenGL.
