Typeclass roughly equivalent to a Lens, which allows getting items out of a tuple.
This is useful because cascading has type coercion (string to int, for instance) that
users expect in the fields API. This code is not used in the typesafe API, which
does not allow suc silent coercion.
See the generated TupleConverters for an example of where this is used
