I understand how DEFTABLE works (I think so), and it doesn't support  
what I actually need.  I want to use DAO inheritance, which is  
supported, but currently to use constraints in DAO tables, I need to  
specify them separately for parent and child class.  DEFTABLE doesn't  
help here, because it allows only to define a specific table, without  
any extension, application of same constraints to "child" tables, and  
so on.  Maybe initialization function taking class or class name as an  
argument would help -- however, it seems to me that constraints belong  
to DAO classes in the same way column types do.
