The problem in my case is that even a group of objects which belong
together might not have even one common attributes.
One idea is to implement a . operator on a basic data type and return the value
for the corresponding field from the "operator function".
E.g.
"select * from TABLE where mytype.mymember='x'"
could call something like
mytype_member_access( mytype, member_name )
Unfortunately I don't have any idea how to handle updates on fields yet.
Does anybody have any advice on that?
