IEnumerable Syntactic Sugar Proposal

What I really want to know is, what is the difference between:

public static IEnumerable<int> GetNumber()
{
        return _numbers.Select(x => x);
}

and

public static IEnumerable<int> GetNumber()
{
        return _numbers;
}

In the first example you return the items lazily whereas in the second you just return the array as is with an implicit cast to IEnumerable<int>.
