If integers were normal objects, the first would mean they would be sindletons. The second means you can't change them, you can only change a variable to hold a different value. It also means you can't add instance variables to an integer, neither singleton_methods. And the third means that if you do change the variable, a passed value will not be changed. Also they are not garbage collected. If you noticed how weird that idea is (the gc), you can see how natural is that Value idea.

Instead of trying to make this difference go away (like MRI) I think it should be explicit and indeed be expanded to all Objects that have these properties. Words for examples (ruby calls them Symbols), are the same. A Table is a Table, and Toble is not. Floats (all numbers) and Times are the same.
