Part of the goal is to establish a template as a subtly different thing from the type with the same name: it defines the implementation, whereas types don't distinguish between properties with the same types but different implementations.
The compiler currently calls templates "class types", for example when you are told you can only inherit from a class type. But a trait is also a "class type". I think the rule is clearer when types aren't even mentioned: simply put, a template can inherit from another template.
http://scala.zone has a whole section on templates, and a different section on types. So far, it hasn't been too much of a problem deciding which of the two sections each lesson belongs in.
