[FR-devel] Database slot-type addtion

[Rich Kilmer]

Proposed addition of a slot type of 'hash':

Added methods to slot:

 #slot.put(key, value) 
 #slot.get(key) #=> value
 #slot.is_hash_slot? 
 #slot.hash # turn slot into hash slot

Right we could just set the data to a hash like this:

 slot.data = {}
 slot.data[key]=value
 slot.data[key] #=> value

But modifying the internal object's state as stored in a data slot does
not propagate notifications events, whereas the new method (hash slot)
would allow a subscriber to be notified.

Thoughts?
