That's why I wrote an example of an External Method that does a check on 
the length of the range, which has subsequently been turned into an 
addition to Zope 2. In Zope 2 you can do:
  <dtml-in "_.range(0, number_of_times)">
     <!--Do your worst-->
  </dtml-in>

The _.range method does everything the bog standard python range() does, 
but won't let you make a range that contained more that 999 elements (like 
range(0, 20000, 3)).
