+When non-C<NULL>, the function pointed by this variable will be called each time an OP is freed with the corresponding OP as the argument.
+This allows extensions to free any extra attribute they have locally attached to an OP.
+It is also assured to first fire for the parent OP and then for its kids.
+
+When you replace this variable, it is considered a good practice to store the possibly previously installed hook and that you recall it inside your own.
