NAME
push - push one or more values into the front of a list
SYNOPSIS
push(x, y_0, y_1, ...)
TYPES
x lvalue whose value is a list
y_0, ... any
return null value
DESCRIPTION
If after evaluation of y_0, y_1, ..., x is a list with
contents (x_0, x_1, ...), then after push(x, y_0, y_1, ..., y_n-1),
x has contents (y_n-1, ..., y_1, y_0, x_0, x_1, ...), i.e. the
values of y_0, y_1, ... are inserted in succession at the beginning
of the list.
This function is equivalent to insert(x, 0, y_n-1, ..., y_1, y_0).
EXAMPLE
; A = list(2,"three")
; print A
list (2 elements, 2 nonzero):
[[0]] = 2
[[1]] = "three"
; push(A, 4i, 7^2)
; print A
list (4 elements, 4 nonzero):
[[0]] = 49
[[1]] = 4i
[[2]] = 2
[[3]] = "three"
; push (A, pop(A), pop(A))
; print A
list (4 elements, 4 nonzero):
[[0]] = 4i
[[1]] = 49
[[2]] = 2
[[3]] = "three"
