Heh. I sort of feel that adding procedural macros to a language with a complex syntax and semantics like Swift doesn’t make much sense at all. I would be pretty strongly opposed to any macro system proposal unless a compelling case could be made that it would improve implementation quality by significantly simplifying the code (for example, by moving parts of the type checker into the standard library).
