What would be the fastest way to move every value in a list up one position in the list (thus deleting the last number in the list, and adding a new one at the beginning)?

Example:
{1,2,3,4,5->L1
//What would I do here?
#->L1(1
L1 = {#,1,2,3,4

c1-->
CODE
ec1?List(cumSum(L1→L1c2
ec2(A lot faster during 100 repetitions) and smaller by 10 bytes.

That cuts out the first element and doesn't add on a new one.

@trevmeister66, if you wanted to move everything down (left in your list) and cut off the first element and add a new number to the end(which is the exact opposite of what you're doing now) you can use c1-->
CODE
ec1?List(cumsum(augment(L1,{Nc2
ec2
which is 7 shorter.  All you would have to do is switch your list around.
