/// @assertion Not using inference on the implicit arguments means that we won’t
/// apply implicit coercions, like downcast from dynamic or .call-tear-off if
/// assignment from the declared type of a super parameter to a
/// super-constructor parameter’s type requires it.
/// For example: C(dynamic super.x) : super(); will not be inferred to be
/// C(dynamic super.x) : super(x as int);, it’s just a compile-time error that
/// dynamic is not a subtype of int, just as it is for redirecting
/// factory constructors.
