Edit Question
Title
Body
I was going through Edulinq by Jon Skeet, and I came across the following code, Page 23, in which he implements cache mechanism for Empty() operator of Linq private static class EmptyHolder<T> { internal static readonly T[] Array = new T[0]; } My question is, how does this actually cache the Array variable? Optionally, How does it work in CLR? Edit: Also following that, he mentions there was a revolt against returning an array. Why should anybody not return an array (even if it is 0 sized?)?
