Because Interval>>species is Array. This lets us re-use the generic collection methods instead of having to re-implement them for little benefit. > Returning an Interval is more intuitive to me > since the copyFrom:to: message is being sent > to an Interval. > Of course, for the the example above at least, > it is more efficient as well. It would only be more efficient if it ever got used. Can't imagine a case where this would be useful. It would add complexity to the implementation though. - Bert - _______________________________________________ Beginners mailing list Beginners@lists.squeakfoundation.org http://lists.squeakfoundation.org/mailman/listinfo/beginners
