[Cuis-dev] Subclassing SmallInteger for representing numerical things?

[Casey Ransberger]

We get taught to subclass something when we need an object with custom behavior, but that isn’t always the best plan. With simple (VM-primitive) things, you’re better off creating a class and then sticking the smallint in an instance variable. 

Basically: there’s usually not a need to subclass classes that represent primitive values. Just use instances of them in your own class based on Object or anything you want to inherit from.
