[apluslist] Dictionaries

[Steven H. Rogers]

Dictionaries are very useful data structures with efficient hash table 
based implementations Python and K.  Slotfiller seems to be the closest 
analog in A+, with the pick function used for access. 

Is this hash table based, more like an association list, or something 
else entirely? 

Is it suitable for large dictionaries or indexes? 

Is there a complementary function to pick for adding a name value pair 
to a slotfiller?
