"Limits of Lifetimes" example now compiles

[natsukagami]

struct Foo;

impl Foo {
    fn mutate_and_share(&mut self) -> &Self { &*self }
    fn share(&self) {}
}

fn main() {
    let mut foo = Foo;
    let loan = foo.mutate_and_share();
    foo.share();
}

The above example, from https://doc.rust-lang.org/stable/nomicon/lifetime-mismatch.html, should now (as of Rust 2018), compile. I guess it is because of NLL, but I am not 100% sure.

Example ran on Rust Playground compiles with Rust 2018 but doesn't on Rust 2015 (with the error explained in the book).

I think this should be fixed by #101.

I see! Closing now.
