 The reason for 5.4, among other things, is that we can now dereference an array directly from a function call:
 
-    $ciscosw->useCisco_VTP()->vlanNames()[ $vlanid ]
+    $name = $ciscosw->useCisco_VTP()->vlanNames()[ $vlanid ];
 
 rather than the old way:
 
     $vlanNames = $ciscosw->useCisco_VTP()->vlanNames();
-    $vlanNames[ $vlanid ]
+    $name = $vlanNames[ $vlanid ];
 
 And as most of the defined MIBs *walk* a given tree, almost all defined functions return an array.
