/**
 * @assertion The result of a lookup of a getter (respectively setter) m in class C with
 * respect to library L is: If C declares a concrete instance getter (respectively setter)
 * named m that is accessible to L, then that getter (respectively setter) is the
 * result of the lookup. Otherwise, if C has a superclass S, then the result of the
 * lookup is the result of looking up getter (respectively setter) m in S with respect
 * to L. Otherwise, we say that the lookup has failed.
 * @description Checks that if there are appropriately named getters in several classes in C's hierarchy,
 * only the one from the class closest to C is returned and the subclasses are not considered.
