// 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.
