Classy MTL extension of the lovely Opaleye library, which simply just wraps things up in a MonadReader , MonadError context where the config & error are constrained by Classy Lenses & Prisms rather than by concrete types

More info on this pattern can be found in George Wilson's BFPG talk : http://talks.bfpg.org/talks/2015-06-09.next_level_mtl.html
