Subject: Re:  list operators

Sorry, but what I mean is

	(left) shift

	; * = ( 1 2 )
	; echo $*
	1 2
	; shift
	; echo $*
	2
	; shift
	; echo $*

	; shift
	cannot shift

	right shift

	; * = ( 4 5 6 7 )
	; echo $*
	4 5 6 7
	; shift -3
	; echo $*
	4

and dropping one element from a list:

	* = ( 1 2 3 4 )
	; echo $*(-3)
	3
	; echo $*
	1 2 4
