+// Test that we do not currently display `~const` in rustdoc
+// as that syntax is currently provisional; `~const Destruct` has
+// no effect on stable code so it should be hidden as well.
+//
+// To future blessers: make sure that `const_trait_impl` is
+// stabilized when changing `@!has` to `@has`, and please do
+// not remove this test.
