* `!` to any `T`
#### Slice DST raw pointer conversions
When `T` and `U` are both "slice DSTs" - ie, slice types or types whose trailing field
is a slice type - the raw pointer types `*const T`, `*mut T`, `*const U`, and `*mut U`
encode the number of elements in this slice. Coercions between these raw pointer types
preserve the number of elements. Note that, as a consequence, such coercions do *not*
necessarily preserve the size of the pointer's referent (e.g., coercing `*const [u16]`
to `*const [u8]` will result in a raw pointer which refers to an object of half the size
of the original).
### Unsized Coercions
The following coercions are called `unsized coercions`, since they
