In this series of presentations, we examine different strategies for creating a Common Lisp implementation, as well as the pros and cons of each strategy. We assume basic knowledge about how a typical modern operating system (such as Unix) works, and how traditional batch languages (such as C) are compiled and executed on such a system. We furthermore assume medium-level knowledge about Common Lisp. In part 2, we sketch a possible compiler that generates byte codes, and an abstract machine for interpreting such byte codes.
