 SQL++ is a highly composable expression language. Each SQL++ expression returns zero or more data model instances.
 There are three major kinds of expressions in SQL++. At the topmost level, a SQL++ expression can be an

-alternative values), or a QuantifiedExpression (which yields a boolean value). Each will be detailed as we
