In theory, but there's for sure no actual vector-implementation
where this doesn't work as long as you don't read from or write
to the reference.
The theory bases on architectures which might check the pointers
inside the references when they're loaded to a register. F.e.
CPUs with segment-registers might load the segment and the seg-
ment might get checked; but such architectures aren't of any
importance today.
