/**
 * @assertion A constant expression is an expression whose value can never
 * change, and that can be evaluated entirely at compile time.
 * A constant expression is one of the following:
 * . . .
 * • A constant constructor invocation that is not qualified by a deferred
 *   prefix.
 * @description Checks that a value created using constant constructor can be
 * an element of a constant list literal and is, therefore, a constant
 * expression.
