 In this post, I am proposing "Stacked Borrows": A set of rules defining which kinds of aliasing are allowed in Rust.

 However, in Rust, we cannot talk about references and whether the are valid at their given type without talking about lifetimes.
 With "Types as Contracts", the exact place where a lifetime ended turned out to be really important.

+Not only did this make the specification complex and hard to understand; the implementation in Miri also had to actively work against the compiler's general intention to forget about lifetimes as early as possible.
 With non-lexical lifetimes, the "end" of a lifetime is not even so clearly defined any more.

 For each of these operation, we iterate over all affected locations; let us call the loop variable `loc` of type `MemoryByte`.
 We also have a variable `tag` with the tag of the pointer we are operating on (loading, or storing, or casting to a raw pointer, ...).

 It is just easier to answer these questions when you do not have to *manually* reevaluate all examples after every tiny change.
 However, I can always use more examples, so if you think you found some interesting or surprising corner case, please let me know!
