Absolutely. I have a book about Eiffel that takes as a first example of
OOP... an expression evaluator.
Every time you encounter a (sub)expression, you create an "expression"
object, call its "evaluate" method, and then destroy the object...

Like M. Gauthier likes to say: "not everything is an object"
