The article mentions expanding capabilities to support self-referential structs. Currently structs are allowed to borrow from any data outside of them, but not from any of their own fields. Rust doesn't want to have move constructors, and borrowing from inline fields can't be safe, but borrowing from heap-allocated data owned by the same struct should be possible, and currently there's no non-hacky way to express that.
