Or even more generic by chaining two slices in case the range permits it:

auto rotatedView(R)(R range, long n = 1)
if (...)
{
	if (n == 0) return range;
	...
	n %= range.length;
	...
	return chain(slice1, slice2);
}

Used something like that in previous advent of code challenges where they expect you to go for doubly linked lists due to large buffer size.
