Ar an ceathrú lá déag de mí Lúnasa, scríobh Stephen J. Turnbull: 1) Interpreted code that uses the multiple-values functions consistently will continue to work in as far as it ever did in 21.4, and will work correctly in 21.5-with-multiple-values. 2) Code compiled by 21.4, that uses the multiple-values functions, and without patch http://mid.gmane.org/19070.60359.500812.167386＠parhasard.net, will have subtle problems when run in 21.5 with the multiple-values patch. This is because it assumes that #'values is an alias for #'list, and that #'values-list is an alias for #'identity, and that these aliases are available at runtime. Most of the package changes just remove the third assumption, and the forms that deal with multiple values (the expansion of #'multiple-value-bind, most relevantly) continue to get presented with lists. 3) Code compiled by 21.4 and executed by it, that uses the multiple-values functions, will work correctly in as far as it ever did. 4) Code compiled by 21.5-with-multiple-values and executed by it, that uses the multiple-values functions, will work correctly. 5) Code compiled by 21.5-with-multiple-values and executed by 21.4, that uses the multiple-values functions, will throw an error at the start of the file. 6) Code compiled by 21.5-without-multiple-values, that uses the multiple-values functions, will work as far as it ever did. (Also, by “telling people” I meant telling the beta testers encountering the subtle problems in 2) how to address them, not talking with Vin or Norbert.) -- ¿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
