Thanks for sharing that, Slava! Reading that really helped me gain a better understanding of how the current reflection model works and how it could be extended.
Although my intended use cases are more for in-process type-level reflection akin to objc_copyClassList and class_copyPropertyList. In any case, swift-dev isn't the best place to discuss this, so I'll synthesize my thoughts into a swift-evolution proposal shortly.
