1) Rewrite your application so that you are using "shift" instead of
   running through the positional parameters backwards.

2) Copy the positional parameters to an array and then use unset on the
   array.

3) Use the "range" notation to generate a list of all the positional
   parameters except the last one, and then reassign the lot of 'em.

That's in order of preference.
