As I said, numeric types and arithmetic was only a trivial example,
though there are advantages in treating them as objects if it can be
done without significant performance penalty. Smalltalk was the first
object-oriented system that treated even primitive numeric types as
objects, but Simula-67 did not, nor do many of the more recent
object-oriented systems.  Java primitive types aren't really objects,
but by means of an "autoboxing" feature, can be treated as though they

Some object-oriented environments actually do provide that, including Python.
