Tim,

I see that for a List[T], there is both a class method Reverse() and an extension method Reverse()

For a Stack[T], there's only an extension method

Ok - the extension method you mentioned rings a bell - it returns IEnumerable[T] in reverse order and hence does not alter the stack

-		yy	{System.Linq.Enumerable.ReverseIterator<int>}	System.Collections.Generic.IEnumerable<int> {System.Linq.Enumerable.ReverseIterator<int>}

eg

		static void TestStack3()
		{
			var xx = new Stack<int>();
			xx.Push(3);
			xx.Push(2);
			xx.Push(1);

			var yy = xx.Reverse();

	
			//xx.Reverse(); // should get 3, 2, 1 but still get 1,2,3

			Console.WriteLine("Stack3 ");

			foreach( var v in yy)
				Console.Write("{0} ", v);
			Console.WriteLine();
		}
