This has not changed since Smalltalk-80. Running Smalltalk-80 and looking in the browser, I see Dictionary>> do: aBlock super do: [:assoc | aBlock value: assoc value]. 'super' here is Set, a Dictionary being implemented as a Set of Associations (which was always a bad idea). Dictionary>>do: has ALWAYS iterated over the elements of a dictionary, NOT the associatons. I have Squeak, Pharo, Smalltalk-80, VisuaWorks, VisualAe, Smalltalk/X, and GNU Smalltalk (plus several others including my own). They all follow the ANSI standard in this respect., The distinction between #do: and #associationsDo: goes back to Smalltalk-80, as does #keysDo:.

So there we already have dialect differences â¦

AI knows little about Smalltalk ;-)
You can use do: with each Association as a parameter or you can use keysAndValuesDo:
myDic do: [:assoc| | key value| key := assoc key. value := assoc value. ...].
myDic keysAndValuesDo: [:key :value| ...]

I need to iterate over a dictionary.
I asked the AI buddy for a little help, and he says:
| myDictionary |
"Create a dictionary" myDictionary := Dictionary new. myDictionary at: 'one' put: 1. myDictionary at: 'two' put: 2. myDictionary at: 'three' put: 3.
"Iterate over the dictionary" myDictionary do: [ :key :value | Transcript show: key , ' -> ', value printString ; nl. ].
but when i try this, I get:
ArgumentsCountMismatch: This block accepts 2 arguments, but was called with 1 argument.
Is the AI using a different dialect of smalltalk?
how would I go about acting on each pair?
Thanks!
