> Scheme & LISP have no built-in classes, and one can argue that CLOS CLOS is built-in. > CLOS isn't what we normally describe as OOP There is no 'normal' description of OOP.

CLOS has classes, instances, inheritance, dispatch, and other features of OOP. > Both normally have a global namespace. Namespaces for symbols in Common Lisp are called 'packages'.
