Right, you surely remember the thread (http://www.jsoftware.com/pipermail/general/2000-October/004707.html ) and almost a decade later the issue is still been discussed even after straightforward answers by Roger. As you are also aware, the evaluation order does not matter for a functional programmer in terms of the results (http://www.jsoftware.com/pipermail/programming/2007-December/009126.html ) but it could in terms of performance with the possibility of parallel processing ( I know, a cynic could say: J is ideally positioned for parallel processing *and it always will be* ;)
