-Not only did this make the specification complex and hard to understand; the implementation in [Miri]({% post_url 2017-06-06-MIR-semantics %}) 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`.

 For example, in `&Cell<i32>`, all 4 locations are inside an `UnsafeCell`.
 However, in `&(i32, Cell<i32>)`, only the last 4 of the 8 covered locations are inside an `UnsafeCell`.

 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!
