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:.
