Then why was C++ invented? What you have described can be done in C,
Pascal, and Fortran 90, all of which are generally classified as
procedural programming languages. As Lutz and Ascher say in "Learning
Python", in object-based programming one can pass objects around, use
them in expressions, and call their methods. "To qualify as being truly
object-oriented (OO), though, objects need to also participate in
something called an inheritance hierarchy." Whether true OOP is a Good
Thing is arguable and depends on the situation.
