2022-01-12spec: adjust rules for specific types once moreRobert Griesemer
Introduce a (local) notion of a set of representative types, which serves as a representation/approximation of an interface's actual type set. If the set of representative types is is non-empty and finite, it corresponds to the set of specific types of the interface. In the implementation, the set of representative types serves as a finite representation of an interface's type set, together with the set of methods.

2021-12-13spec: fix conversion rules (match implementation)Robert Griesemer
As written, the conversion P(x), where P and the type of x are type parameters with identical underlying types (i.e., identical constraints), is valid. However, unless the type of x and P are identical (which is covered with the assignability rule), such a conversion is not valid in general (consider the case where both type parameters are different type parameters with constraint "any"). This change adjusts the rules to prohibit type parameters in this case. The same reasoning applies and the analogue change is made for pointer types. The type checker already implements these updated rules.
