The persistance/streams stuff havn't really been a concern of mine, so I will not comment on that. As for the instansiation complexity, Yes, it can be complex, but somehow I've always managed. I guess that it took an hour or so the first time with a lot of digging around in the source. But once one get the feel for it the biggest problem is IMHO to com up with sensible names for the 'intermediate' packages/types. Sometimes I really whish that Ada would provide anonymous types. *smacks my fingers with the ruler and tell myself to stop ranting* -- Mats Karlssohn, developer mailto:mats@mida.se Mida Systemutveckling AB http://www.mida.se Box 64, S-732 22 ARBOGA, SWEDEN Phone: +46-(0)589-89808 Fax: +46-(0)589-89809
