Those examples provide an overall simplification for common constructs. As the 'use' docstring says, it is "Like 'require, but also refers to each lib's namespace using clojure.core/refer." so it explicitly combines two already somewhat complex operations. When we added :refer to 'require' we also complected things but we improved expressiveness and we allowed the overall 'ns' construct to be more uniform and consistent so I think, on balance, that was a win (and I certainly like having one construct - :require - in my ns declarations rather than a mix of :use and :require). We probably should have taken that opportunity to deprecate :use at the same time but as I recall, :refer was added very late in the cycle and arguing over deprecating :use would have detracted from the discussion of the utility of adding :refer to :require in the first place. -- Sean A Corfield -- (904) 302-SEAN An Architect's View -- http://corfield.org/ World Singles, LLC. -- http://worldsingles.com/ "Perfection is the enemy of the good." -- Gustave Flaubert, French realist novelist (1821-1880) -- -- You received this message because you are subscribed to the Google Groups "Clojure" group.
