>>>>A long time ago I wrote an IEnumerable to create a Fibonacci series - but lost it. Now I came up with this:

static IEnumerable<double> FibonacciSeries(int count)

>>>>                yield return y = x + y;
>>>>            }
>>>>        }

but I've a feeling that the old, lost, version was more concise. Anyone see a way of improving the above ?
