/// @assertion It is an error if a class declaration declares an instance
/// variable with a potentially non-nullable type and no initializer expression,
/// and the class has a generative constructor where the variable is not
/// initialized via an initializing formal or an initializer list entry, unless
/// the variable is marked with a `late`, `abstract`, or `external` modifier.
///
/// @description Check that it is no error if an instance variable with a
/// potentially non-nullable type has no initializer expression but initialized
/// in a constructor via an initializing formal or an initializer list entry.
/// Test some class `A`.
