2 + 3 Where's the essential complexity here? Sure, the numbers are important, but do either of them "own" the plus? If so, where does it belong, does 2 have the capability to have another number added to itself, or does 3 have the capability to be added to another number?
Or, is `+` a standalone verb in its own right? a concept related to numbers in general but not specifically tied to any one of them. In pure OO theory, `+` must be defined as a member on the value 2, so we would send the message `+` to that integer with a parameter of `3` Statics won't help you reason about this either, nor will primitives, as neither concept is acceptable in pure OO.
