this is precisely why i don't like that in

  arr.each { |elem|
    max = ...
  }
max could be in the global scope - i'm a C programmer and this simply seems
bizarre.

now

  arr.each { |elem|
    keyword max = ...
  }

where keyword is something like 'static' or 'export' implying that the var is
on the heap and globally available make sense to me.
