Wow, this is an impressive amount of high-level feel for relatively little preprocessor code (and a fairly lightweight C library underneath that). Holds together pretty consistently, which is hard to do with syntax extensions built on top of the C preprocessor, vs in languages with more convenient syntax-extension or macro systems.
