/// @assertion It’s a compile-time error if a super-parameter in any declaration
/// other than a non-redirecting generative constructor.
///
/// All non-redirecting generative constructors have a super-constructor
/// invocation at the end of their initializer list. If none is written (or
/// there is even no initializer list), the default is an invocation of super(),
/// targeting the unnamed superclass constructor. It’s a compiler-time error if
/// the superclass does not have the specified constructor, or it’s not a
/// generative constructor.
