AFAIR this does not create new classes, since it's the same code, and
same code means same class. But eval() has new code every time, thus new
class. Generally I don't think PHP has any operation that can destroy an
existing class. It won't be easy too since you don't know whether there
are any objects of this class around (unless you're in shutdown).
