/**
 * @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.
 * @description Checks that simple bounds are correct for non-function type
 * aliases with list and map parameters: [A<X extends List>], [B<X extends Map>]
