/// @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:
/// . . .
/// • An expression of one of the forms ~e, e1 ^ e2, e1 & e2, e1 | e2, e1 >> e2
///   or e1 << e2, where e1 and e2 are constant expressions that evaluate to an
///   integer value or to null.
/// @description Checks that various expressions of the specified forms can be
