/**
 * @assertion Given a switch statement which switches over an expression e of
 * type T, where the cases are dispatched based on expressions e0...ek:
 *
 * - It is no longer required that the ei evaluate to instances of the same
 *  class.
 * - It is an error if any of the ei evaluate to a value whose static type is
 *  not a subtype of T.
 * - It is an error if any of the ei evaluate to constants for which equality
 *  is not primitive.
 * - If T is an enum type, it is a warning if the switch does not handle all
 *  enum cases, either explicitly or via a default.
 * - If T is Q? where Q is an enum type, it is a warning if the switch does not
 *  handle all enum cases and null, either explicitly or via a default.
 *
 * @description Check that it is a warning if T is an enum type and the switch
 * does not handle all enum cases, either explicitly or via a default.
