You move variables closer to where theyare used, therefore reducing clutter in the main "var" section.Limiting variable scope is definitely a good thing, I sure hope you'renot arguing against that. That's why almost all languages encourage it.
Agreed, and that's /particularly/ the case with something like a loop control variable which should not be assumed to have a predictable value out-of-scope.
Wirth moved variables outside blocks to make Pascal incompatible with ALGOL, since after the disastrous ALGOL-68 fiasco he wanted to plough his own furrow. That doesn't necessarily make the decision a wise one.
