Yes, that is indeed an idea, but the details will determine how to proceed .. typeclasses are very 'generic' and the details of most real systems are intricate and hard to abstract. -- John Skaller <skaller at users dot sf dot net> Felix, successor to C++: http://felix.sf.net ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
