Ar an ceathrú lá déag de mí Lúnasa, scríobh Stephen J. Turnbull: Right, that’s what http://mid.gmane.org/19070.60359.500812.167386＠parhasard.net does. However, Norbert’s quicker about making modified packages available than Vin is about making modified 21.4 versions available (something which is as it should be), and I’m more comfortable telling people who encounter the incompatibility to install a package from the beta/experimental directory than to wait until there’s a 21.4 release and there are new .tar.gz files for all the affected packages. Some of the package patches are distinct, though. They are examples where multiple-value-bind was never conceptually correct (that is, there wasn’t a corresponding #'values call, just one to #'list or something analogous), and #'destructuring-bind or a non-erroring analogue is better code in those contexts. That reminds me; the multiple-values patch makes #'throw into a special form, since it needs to examine its arguments into a way that functions don’t (#'throw is also a special form, sorry, special operator in Common Lisp, for the same reason.) It also has a special bytecode for throw. Now, code compiled by 21.5 with the multiple-values patch that uses the multiple-values functionality will refuse to run on 21.4; which is fair enough, as far as I can see. Code that uses #'throw (that is, most code), is also affected, though there is a separate check at the beginning of every file; I wonder is it reasonable to add a minimal patch to 21.4 to support the throw bytecode. Hmm? Not in a significant way; it’s just that the alias now takes effect at compile time, not runtime, something we know worked fine in 21.5 for years. -- ¿Dónde estará ahora mi sobrino Yoghurtu Nghe, que tuvo que huir precipitadamente de la aldea por culpa de la escasez de rinocerontes? _______________________________________________ XEmacs-Patches mailing list XEmacs-Patches(a)xemacs.org http://calypso.tux.org/cgi-bin/mailman/listinfo/xemacs-patches
