AST does stand for abstract syntax tree and they are much more like Lisp
macros as opposed to the C preprocessor.
Too bad nothing happened. He promised AST macros, but it will probably
still take several years before we have a preliminary implementation and
maybe 10-20 years before a written spec & almsot bug-free implementation.
Part of what happened was that at the conference, I showed that the
functionality of string mixins was a superset of what was planned for
AST macros. Since that time, there has not been any kind of proposal, or
even a concept. So it's a bit meaningless to talk about "AST macros"
right now as if they were a planned-but-not-yet-implemented feature.
