Abstract
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 pieces, while still providing the flexibility to radically change the syntax and semantics of the programming language.
In this talk, I will give a high-level overview of the myriad of programming languages that Racket supports, as well as an overview of the research area of macros, showing what can be accomplished with them and introducing some the associated technical challenges (and their solutions).
