Am I right to think that they are similar?
I think they are similar, but two key differences are: - An AST transformation can transform existing syntax but doesn't allow you to create new syntax. - An AST transformation has to be explicitly invoked. A macro is part of the language proper and has a semantics for how and when macros are evaluated.
