It has its flaws, but it's useful in many circimstances nonetheless.=20
I've used, named tl, instead, a few times when I new the first argument=20
to a fn would be a word, and I needed to shift it off, and as the=20
following arguments had been parsed by the shell to begin with, I knew=20
they'd be parsed the same again.

Nevertheless, here's an unpleasant rc solution:

fn myshift {
	* =3D $$1
	eval 'shift; '$1' =3D $*'
}

Or, you can just use sh(1), where you have ${tl}, subfn,
(hd tl) :=3D list
and so forth.

There is no safety in numbers, or in anything else.
