| // 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.
