/**
 * @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 declared abstract getters and setters are skipped
 * in a lookup.
