Opaque class

Wrap an type and make it opaque by not exposing and allowing only usages to it with specific operations defined in the library that defined this type using the member named _unwrap.

Optionally the unnamed constructor can be exposed, with exposeConstructor in case an const constructor is needed.

This is the mostly equal to Record with the body {#_unwrap: type}
