In general I agree with the author; arrays should be a core type. They are simple to implement in the compiler, and a significant number of types can be created on top of arrays. On the other hand, I think the author got at his conclusion by looking at the current feature-set of existing languages. What if a new language were created that either negated the need for arrays all together; or implemented core types that allow for complete creation of an array type in a library?
