g) default values for unspecified attributes
Another thing that comes to my mind is that sometimes one could need to atomically give a sequence of values to an attribute. This could be done with a function to lock an attribute: lock :: Attribute a -> IO (Attribute a) release :: Attribute a -> IO () where the result of a lock operation is an attribute wich is a representation of the original one, and the only one allowed to make modifications until release, or perhaps in a simpler way with putList :: Attribute a -> [a] -> IO () Someone wants to comment on this?
