We are considering 2 alternative approaches to supporting extensible protected types, one which is based pretty closely on the TOPLAS article, and one which is significantly simpler, based largely on work done during the original 9X process. For the "simpler" approach, see: http://www.ada-auth.org/cgi-bin-acats/cvsweb.cgi/AIs/AI-00250.DOC?rev=1.2 The one more closely based on the TOPLAS article hasn't made it into the ada-auth database yet. > Cheers, > > Nick Williams. -- -Tucker Taft stt@avercom.net http://www.averstar.com/~stt/ Chief Technology Officer, AverCom, Inc.
