/// @assertion Let [G] be a generic class or parameterized type alias with formal
/// type parameter declarations [F1] .. [Fk] containing formal type parameters
/// [X1] .. [Xk] and bounds [B1] .. [Bk]. We say that the formal type parameter
/// [Xj] has a simple bound when one of the following requirements is satisfied:
/// [Bj] is omitted.
/// [Bj] is included, but does not contain any of [X1] .. [Xk]. If [Bj] contains
/// a type [T] on the form qualified (for instance, [C] or [p.D]) which denotes a
/// generic class or parameterized type alias [G1] (that is, [T] is a raw type),
/// every type argument of [G1] has a simple bound.
