 The short version is that I view Rust types with private invariants as not having just a single invariant, but different invariants that reflect the different "modes" the type can be in.
 @cramertj suggested to use "typestate" as terminology here, and I agree that this makes sense.

 `Pin` lets us give a type to `SelfReferantial` that makes it safe to use.
 This is in the best tradition of Rust: We are using an expressive type system to provide safe APIs for operations that only have unsafe APIs in other languages (e.g., iterators that avoid iterator invalidation which plague even memory safe languages like Java).
 In the following, I will explain how one can prove that our claim of safe encapsulation actually holds true.
