If you happen to know the compleat set of loop values prior to
entering the loop, then yes, you can use various sorts of range(),
or dtml-in over a list value to do it.  However, that's not the
general case of a loop (which contains a conditional as he showed),
and DTML just doesn't attempt to handle looping constructs where the
loop termination conditions are determined during the execution of
the loop.
