That depends on what you want to store and/or how those are implemented.
As an example how to implement a Stack and a Queue, you might want to
take a look at

http://www.knuddel.org/Projects/KoKit/Documentation/KoFoundation/KFStack.html
http://www.knuddel.org/Projects/KoKit/Documentation/KoFoundation/KFQueue.html

and the respective source in CVS.

Assuming that -newWithValue: returns an object, this would be correct,
although 10000000000 might result in an overflow.

I wouldn't call the method _new_WithValue:, as the 'new' implies a new
instance of MyObject, instead [anObject addValue: i] or [anObject
addInteger: i] (addFloat: addLong: ... you get the idea) would be a
better name.
