OK, a closql-object(This is a class defined in closql) is a proxy object to a
row in SQL database. So each time user tries to read a slot, closql must sync
values between database and Emacs first.
It's also possible to reinvent accessors for closql specific usage, but Jonas
doesn't do. I guess this way(hack on EIEIO) can reuse some facilities(like with-slots).
