Building new programming languages from whole cloth is a difficult proposition at best. Macro system provide an alternative; they support the construction of new programming languages from existing existing pieces, while still providing the flexibility to radically change the syntax and semantics of the programming language.In this talk, Robby Findler, associate professor of electrical engineering and computer science at Northwestern University, will give a high-level overview of the research area of macros, showing what can be accomplished with them and introducing some of the technical challenges they pose.
