The binding form doesn't provide the semantics of temporary redefinition. Rebinding is quite a different beast in many ways. The way it handles metadata makes sense to me. I don't see why :macro and :arglists need to reside on the var rather than the function itself and it indeed does lead to some surprises in odd corner cases. But it is certainly logical and proper that :file and :line reside on the var. Anyway, I hope this excursion was enlightening. It forced me to reinforce my understanding of some of these issues. -Per -- You received this message because you are subscribed to the Google Groups "Clojure" group.
