About being premature ‒ since typing ecosystem evolves much faster than Spark it might be preferable to keep annotations as a separate project (preferably under AST / Spark umbrella). It allows for faster iterations and supporting new features (for example Literals proved to be very useful), without waiting for the next Spark release. -- Best regards, Maciej Szymkiewicz Web: https://zero323.net Keybase: https://keybase.io/zero323 Gigs: https://www.codementor.io/@zero323 PGP: A30CEF0C31A501EC
