I don't get it. How many types do I need, before the kind of data I am talking about becomes better represented by an object comprised of smaller pieces?
Why would I want to spend my time "type level programming"?
Maybe I don't understand what's meant by a type. Is it on the level of string/double/int, or is it expected to cover more (string with a well formatted ISO 8601 datetime, etc)? What is accomplished that couldn't be done in vanilla Ruby with an object representing a more complex datatype with its own getters/setters to cover validation?
