Overview

This class is used to represent complex SQL expressions, so that queries can return expressions. This is also meant to be used for conditions in a WHERE clause. There are no utility classes for generating these (even though they’ll probably include field names and other kinds of values), but for convenience, they can be generated with Kernel#SQLFunc.
