When a programming question is asked on MathGroup, often many completely different solutions are posted. Anyone (especially someone who has used Mathematica extensively since version 1.0, like AES) should be able to compare these solutions and form one's own judgement: which is more concise? more readable? easier to come up with? faster? less memory-hungry? A philosophical debate about the merits of using something called "functional style" in Mathematica does not lead anywhere. Different problems require different approaches, and those who use the system for some time will develop a practical understanding of what approach is suitable what problem. Reading MathGroup and taking a look at other people's code does help. If even after several years of experience with Mathematica you can get results more quickly and easily by programming with loops, then just use loops! The fact that many of us do not find this style very effective in Mathematica (and perhaps offer alternatives to new users sometimes) does not mean that we want to "convert" other old users ...
