I can confirm that the point of adding :refer support to :require was to deprecate :use; I suggested this to Rich at the 2011 Conj when he mentioned the ns macro is too complicated, and he agreed it would be a good idea to enhance :require so that it would make :use unnecessary in order to reduce conceptual overhead. I submitted a patch, and it was applied for 1.4.0.
As far as I recall, this discussion was only around :use clauses in the ns macro. I think the clojure.core/use function is still very useful in the repl for things like tracing and pprint and don't foresee it going anywhere. My assumption from our discussion would be that a warning would be added in a near release when :use was detected in the ns macro, and that it would be removed for Clojure 2.0 when backwards-incompatible changes are OK. But that's just my own guess; I don't know if Rich has any plans to do this. -Phil -- -- You received this message because you are subscribed to the Google Groups "Clojure" group.
