Context.object accepts a template or a string name (and now a type flag). Module.object only accepts a string (because a template already has most of the stuff built in and might as well be passed to the Context.object constructor). The gotcha here is the absolute flag, which must now be set appropriately in all cases *except* where the module is constructed with an offset of 0 (whereby it will have no impact).
