The documentation says the modification of pointer values is

Is this simply a compiler bug?
Where are you reading that in the documentation? There's
nothing unsafe whatsoever about assigning one pointer to
another.
Now, pointer arithmetic is unsafe, and that's forbidden in
@safe functions. So, I suspect that you're ether
misunderstanding the documentation and/or the documentation
isn't clear enough.
