/// @assertion Consider a class, mixin class, enum, or extension type
/// declaration `D` with a primary constructor (note that it cannot be a
/// `<mixinApplicationClass>`, because that kind of declaration does not
/// syntactically support primary constructors). This declaration is treated as
/// a class, mixin class, enum, respectively extension type declaration without
/// a primary constructor which is obtained as described in the following. This
/// determines the dynamic semantics of a primary constructor.
///
/// A compile-time error occurs if the body of `D` contains a non-redirecting
/// generative constructor, unless `D` is an extension type.
///
/// @description Check that it is a compile-time error if the body of `D`
/// contains a non-redirecting generative constructor. Test an enum.
