In the section of 'compound-access': "If obj satisfies predicate,
accessor is applied to obj and the result is returned. Otherwise, if obj
is a compound object, accessor is applied to the first subobject that
satisfies obj, and the result is returned. Otherwise, default is
returned."

If I understand correctly, "accessor is applied to the first subobject
that satisfies obj" should be "accessor is applied to the first
subobject that satisfies predicate" (obj -> predicate).  "satisfies obj"
seems to be nonsense.
