>>>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)
>>>        {
>>>            double x = 0;
>>>            double y = 1;
>>>            for (int i = 0; i < count/2; i++)
>>>            {
>>>                yield return x = x + y;
>>>                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 ?

Why write software if you don't think it's any good? ;-)
