In Collection>>gtDisplayOn:, the stream in argument is not used to print the contents of the collection. So the whole collection is printed whereas only a part of the contents has to be printed. The current implementation is: “s nextPutAll: ((String streamContents: [ :stream | self printElementsOn: stream ]) truncateWithElipsisTo: 42).” And it should simply be: “self printElementsOn: s” Isn't it faster to use streamContents:limitedTo:45, and then replace the last three characters by dots without copying the string if the string size is 45? In fact, streamContents:limitedTo: is already called just before gtDisplayOn:. So the stream given to this method is already limited (not to 45 but 1000). Vincent Stephan
