Oh this is super cool. Coming from Java I've long missed JDBI and Rosetta which makes writing SQL Queries in Java a dream. I've toyed around with a similar style interface for python, and looking at this give me hope I can achieve it.

wow big if true. our core codebase is still on psycopg2 and we do this mapping ourselves. type introspective would be very handy for reducing that boilerplate.
