Thoughts on foreach with Enumerable.Range vs traditional for loop

Question

In C# 3.0, I\'m liking this style:

// Write the numbers 1 thru 7
foreach (int index in Enumerable.Range( 1, 7 ))
{
    Console.WriteLine(index);
}

I kind of like the idea. It's very much like Python. Here's my version in a few lines:

static class Extensions
{
    public static IEnumerable To(this int from, int to, int step = 1) {
        if (step == 0)
            throw new ArgumentOutOfRangeException("step", "step cannot be zero");
        // stop if next `step` reaches or oversteps `to`, in either +/- direction
        while (!(step > 0 ^ from < to) && from != to) {
            yield return from;
            from += step;
        }
    }
}

It works like Python's:

• 0.To(4) → [ 0, 1, 2, 3 ]
• 4.To(0) → [ 4, 3, 2, 1 ]
• 4.To(4) → [ ]
• 7.To(-3, -3) → [ 7, 4, 1, -2 ]
