Hmm, I would have hoped that 'put' would work here, but it doesn't:

-----
import std.range;
import std.array;

void main()
{
    {
        Appender!(int[]) arr;
        arr.put(iota(5));  // ok
        assert(arr.data == [0, 1, 2, 3, 4]);
    }

    {
        int[] arr;
        arr.put(iota(5));  // runtime exception
        assert(arr == [0, 1, 2, 3, 4]);
    }
}
