2 tail - create a list of specified size from the tail of a list
14 If 0 <= y <= size(x) == n, tail(x,y) returns a list of size y whose
15 elements in succession have values x[[n - y]]. x[[1]], ..., x[[n - 1]].
17 If y > size(x), tail(x,y) is a copy of x.
19 If -size(x) < y < 0, tail(x,y) returns a list of size (size(x) + y)
20 whose elements in succession have values x[[-y]]. x[[-y + 1]], ...,
21 x[[size(x) - 1]], i.e. a copy of x from which the first -y members
24 If y <= -size(x), tail(x,y) returns a list with no members.
26 For any integer y, x == join(head(x,-y), tail(x,y)).
29 ; A = list(2, 3, 5, 7, 11)
