Look into using lenses to build composable mappers.

This one's a very vague idea... I just thought it would be interesting to see what happens if a lens get translates to a SQL SELECT and a set to a direct UPDATE.
A lens update would translate to a UPDATE with a function, e.g. update table1 set field = field + 1
I have no idea how a composed lens would translate.
It would also lead to a very chatty API.
