Here we've constructed a reference to an anonymous array of three elements
whose final element is itself reference to another anonymous array of three
elements. (The multidimensional syntax described later can be used to
-access this. For example, after the above, $arrayref->[2][1] would have
+access this. For example, after the above, $arrayref-E<gt>[2][1] would have
the value "b".)
Note that taking a reference to an enumerated list is not the same
