Why this zip not stop after iterated through the longest range? thanks!
import std.stdio, std.range ; void main() { auto a = [1,2,3,4] ; auto b = [6,7,8,9] ; auto c = "ABCDE" ; // <= longest range here auto d = "ZYXW" ; auto CNT = 0 ; foreach(p; zip(StoppingPolicy.longest, a,b,c, d)) if(CNT++ < 30) writefln("%s %s %s %s", p[0],p[1],p[2], p[3]) ; else break ; } output: 1 6 A Z 2 7 B Y 3 8 C X 4 9 D W 0 0 E ￿ 0 0 ￿ ￿ 0 0 ￿ ￿ <= this continue infinitely if not supply a stopping _CNT_
