If n is an integer and x is anything, return a sequence consisting of x repeated n times. A negative value for n will silently be treated as zero.
Warning: such sequences do not get automatically spliced into lists containing them.
i1 : {5:a,10:b} o1 = {(a, a, a, a, a), (b, b, b, b, b, b, b, b, b, b)} o1 : List
