Subject: list operators

Just because there's some life sign on this list again:

What I really do miss in rc is orthogonality in list operators.

	There's a left shift "shift [n]", but no right shift.
	I'd like to propose negative shift values to implement this.

	There's a simple way to pick some element from a list, but not
	to drop one. Maybe we could use negative numbers for that too, e.g.
	droppping the fifth element from a list reads "$x(-5)". Then, the
	solution to the annoying problem of dropping the last element from
	a list is "last = $x(-$#x)"

What do you think of this?
Will it break scripts ( besides already broken ones )?
