Description
Currently you can't use unsized types as parameters or return values. There are good reasons to support this, including passing closures to fns and being able to write things like Rc::new(*slice) where slice has type Box<[T]> or what have you.

Research direction

Determine the remaining design questions and scope before proposing an updated RFC; done means the ownership semantics and supported parameter and return-value cases are specified and accepted through the Rust RFC process.
