New submission from Barry A. Warsaw:
operator.attrgetter() is neutered because it only accepts a single
attribute name, but it would really be much more useful if it accepted,
and followed a dotted attribute path, e.g.:
sorted(seq, key=operator.attrgetter('person.displayname'))
Of course attrgetter() would raise AttributeError if the entire path
could not be traversed.
