// The purpose of this feature gate is to make something into a hard error in a
// future edition. Consequently, this test differs from most other feature gate
// tests. Instead of verifying that an error occurs when the feature gate is
// missing, it ensures that the hard error is only produced with the feature
// gate is present in the `future` edition -- and otherwise that only a warning
// is emitted.
