Returning<R> class final

A prepared mutation whose returned SQL rows decode to R.

Every read method executes the entire mutation again. Selecting only its first result does not limit affected rows. Cardinality and decoding errors can occur after the write; let them escape a transaction callback when that transaction must roll back the changes.
