Ben Kolera introduces Opaleye, a composable and typesafe Haskell DSL for generating SQL against PostgreSQL databases.
Ben talks about Opaleye, an extremely composable and typesafe haskell DSL for generating SQL against a Postgres database. It comes with a tutorial and runnable code that should explain things a bit better: github.com/benkolera/talk-opaleye/tree/master/code The slides can be found here: opaleye.benkolera.comWhy it's here

…valent to Applicative plus Category".
if Opaleye were ported to:
1. Category.(.), which can wire things together
2. and ApplicativeDo, to deal with flipping the order of results, dropping them, and duplicating them
would queries be 1 actually more legible, or less and 2 equally optimizeable?
