It is a truth universally acknowledged that a language in possession of homoiconic syntax must be in want of macros. And yet, most industry languages have eschewed anything resembling homoiconicity, leaving syntax transformations either entirely out of reach, or the realm of a brave few. As such, there’s been relatively little exploration of macros as a practical tool, either with respect to their capabilities or limitations. This talk will explore the use of macros in the Clojure community, characterizing what’s been done, what’s been avoided, and what may lie ahead.
