Browsing in Pharo, I found that Dictionary has a subclass KeyedTree, which is in effect a set of nested dictionaries. Retrieval is by quoting a path, which is simply an array of keys. So in your case it would read:
dict1 atPath: #(’key1’ ‘key2’ ‘key3’). This might be more efficient than repeated use of the DNU mechanism. It is not clear (to me, at least) how to construct the nested dictionaries as a KeyedTree in the first place, but this might be an alternative approach.

(((dict1 at: 'key1') at: 'key2') at: 'key3') Are all the brackets really necessary? BR Mike
