I got curious about that code and tried it on several Smalltalk versions.
Here are the results:

Dolphin : Subscript out of bounds error (Array>>at:)
Smalltalk Express : primitive fails in Arrat>>at:
VSE 3.1 : anwers 'Orange'
VisualWorks 2.5.1 : answers 'Orange'
VisualWorks Non-Commercial 3.0 : answers 'Orange'
VisualWorks Beta 5i : raises a SubscriptOutOfBoundsSignal in Core::Array>>at:
VisualAge for Smalltalk 4.5 : answers 'Kiwi'

Who's right?  :)

What's is the ANSI draft saying about such a case?
