Tx for advice. P.S.: I got nested dictionaries after JSON API call at wunderground weather API. To see all the response in Pharo inspector "live" is really great :-) BR Mike On Mon, Apr 24, 2017 at 7:51 PM, Cyril Ferlicot D. <cyril.ferlicot@gmail.com

May I ask: What's the idiomatic way to retrieve values from nested dictionaries?
(((dict1 at: 'key1') at: 'key2') at: 'key3')
Are all the brackets really necessary?

Hi,
To know if brackets are necessary you can use the "Format" option in your method.
Right click -> format
or cmd/alt/ctrl + shift + f
In this case you can just write:
((dict1 at: 'key1') at: 'key2') at: 'key3'.
