If you are ok with using things from std.range you could use something
like this:
```d
import std.range : cycle, drop, take;
import std.stdio : writeln;
int main(string[] args)
{
auto r = [1, 2, 3, 4, 5, 6, 7, 8];
writeln(r.cycle.drop(3).take(r.length));
return 0;
}
```

One of the things we need to settle in Phobos v2 is what to do with

What is the generic way of copying an element? I wonder whether
we have to use isSomeString to

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;

Here we can't use slice assignment instead of the inner loop
because
