I disagree with the parable on that page. Object does not imply
lexical closure. C++ has objects, but does not have lexical closures.
You can understand objects in terms of lexical closures, but not
vice-versa. In the absence of lexical closures, you need to have
public/private distinctions, constructors, and other busy work
occupying the days of the object-only programmer.
