Should the binding for information be associated with the static class of a variable or the dynamic class.
Alice holds a small Mammal - asks Bill ``does this animal give birth to live young''.
Static answer - All mammals give birth to live young - therefore yes.
What if the Mammal is a platypus? Dynamic answer - Platypus lay eggs, therefore no.
Even statically typed OOP languages can use dynamic binding. But may use static type to determine legality of operation.
