Subject: shift

biased as i might be, i'd like to point out the existence of es's
solution to the shift question:
        + no shift builtin
        + ... accepted in subscript arguments, where
                $x(m ... n) means all elements of x between the mth
                mth and nth (inclusive).  if m is omitted, 1 is assumed.
                if n is a omitted, $#x is assumed.

anyway, that's it.  while
        * = $*(2 ...)
is not as clean as
        shift
the flexibility is, imho, worth it.
