Hello André, Have you read my suggestion of keeping the fact to throw an exception on undefined symbols, but deferring the conclusion until the end of the currently compiled/loaded "unit of code" (a single expression in the REPL, a whole file in a compilation step ...) ? I'd be interesting to understand what drawbacks this suggestion, if even realized, would have ? > > > > --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Clojure" group.
