Maybe I'm confused by this particular example, but what languages would allow functions to store the value of the constructor like that without closures? The thing I don't like about closures is that they can get messed up easily, and not even all OO languages support them. I often think of functions as intentionally "stateless", NOT persisting any value. For that a class is used, if anything for safety.
