The reader doesn't do that but you can easily do it yourself if you only want to annotate top-level values. Thinking about this made me realize that it would be nice if the reader reentered itself (as it does in LispReader's readDelimitedList() and a few other contexts) through a var so it could be rebound by a programmer. Then you could inject your own line number annotation into the reader which would apply not only to top-level values (e.g. a vector literal) but also its subvalues (e.g. the elements of the vector literal). -Per -- You received this message because you are subscribed to the Google Groups "Clojure" group.
