...been studying too many functional languages, and for some reason I keep thinking that collections are immutable objects in ST. Must go back and study Squeak some more.
BTW, the message that you gave for VW doesn't seem to be standard in Squeak.
I have that problem in Icon, too. Collections and variables are generally intuitively mutable wherever you put them :-). Sometimes makes for very very elegant code.
