Hi I have the following problem (here below in CCL and LW) CCL: marcoxa$ ccl AM I BEING LOADED? Welcome to Clozure Common Lisp Version 1.5-r13651 (DarwinX8632)! ? (ignore-errors (read)) foo::bar NIL #<CCL::SIMPLE-READER-ERROR #xC48489E> ? LWM: CL-USER 1 > (ignore-errors (read)) foo: NIL #<CONDITIONS:PACKAGE-NOT-FOUND-READER 21BA3B93> CL-USER 2 > Other Lisps behave similarly. I.e. they don't agree on the type of the error that they need to generate. Now, this is a specific case for me: having a consistent READER-ERROR-BECAUSE-THERE-IS-NO-SUCH-PACKAGE-THAT-THE-SYSTEM-KNOWS error signaled would simplify some code writing. Doesn't anybody think that it would be a good thing to have a CDR suggesting an agreed upon extension of the CL standard ERROR/CONDITION hierarchy?
