I'm coming from a easier languages than C. In .NET, Java or JavaScript I would call that thing a variable (or a constant if it's declared as such). In those languages, if I declare that token, without explicitly giving it a value then the value will be whatever `default` is, i.e. `0` for numbers, `false` for booleans, `null` for reference types etc.

What I want is to declare the token that I would use to access the instance of `CommandHandler` as global, but only instantiate the object in the `setup()` method.

What's the correct name for that token?
