Could you give an example of this?  I'm not sure I understand 
what you're saying.  I've used anydbm a bunch of times and other 
than wrapping access in

   d = anydbm.open(DB_NAME, "c")
   # use d as a dict here
   d.close()

and I've never hit any "need to remember to save changes by 
setting the key's value again".  The only gotcha I've hit is the 
anydbm requirement that all keys/values be strings.  Slightly 
annoying at times, but my most frequent use case.
