I want to copy the first n items of a range to an array, I came up with this now:

data = r.take(n).array;

This works partly, because the values of r are not consumed. So I have to call afterwards:

r = r.drop(n);

Now I wonder, if it is possible to do this with one single call, something like

data = r.take_consuming(n).array;
Does there something like this exist?

sure
auto take_consuming( R )( ref R r, int cnt ) {
    auto tmp = r.take( cnt ).array;
    r = r.drop( cnt );
    return tmp;
}
don't thank
