What kinds of operations are available on a recordset?
If we obtain a recordset of model instances (through search() or browse()), what kinds of operations are available? Can recordsets be added (set + set)? Can they be appended to (setA.append(record))?
Does the recordset behave like some well known Pythonic structure (like list)? If not, is there some kind of reference that lists what operations are and aren't available?
