// 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.
