| // Test that we do not currently display `~const` in rustdoc | ||
| // as that syntax is currently provisional; `~const Drop` 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. | ||
