I agree that if $. isn't available you have to use a separate variable, which is hardly a big issue. But my criticism of tying was more a question of avoiding over-engineering than anything else. In addition, non-core modules are effectively prohibited for all the large corporate production environments I've ever worked in. Why 'effectively' rather than explicitly is another tale.
