It’s annoying, but a strict requirement in Swift that any “unsafe” operation be
marked with the word “Unsafe” either at that point or in some enclosing scope.
Unsafe broadly refers to various forms of memory unsafety. Unsafe bytes is
actually safe with respect to pointer aliasing but it is unsafe because
1. It points into memory that it does not own. The developer must do something
to to manage the memory’s lifetime.
2. It does not perform bounds-checking in release mode.
In both those respects, it’s just like UnsafeBufferPointer.
