why such strong feelings?

i do this all the time and think it's very clear :

  n = ARGV.shift

  n.times do |i|
    Thread.new (i) do |i|
      ...
    end
  end

eg.  i _like_ shadowing when the shadow'd variable is the _same_thing_ and
think this makes much more sense than :

  n = ARGV.shift

  n.times do |i|
    Thread.new (i) do |j|
      ...
    end
  end

shadowing is not _always_ bad IMHO.
