Who said anything about this being the easier solution? My post was just to show you that it could be done the same in pugs. You didn't present any point except that yours was shorter so i was pointing out that isn't true. BTW lazy has a different advantage. If its lazy you get it as you need it, so you don't spend time processing until you get to stuff you need. So even if you need it all this can spread the processing time out instead of one giant load period in the begining. when all you are doing is printing out the matches that doesn't help much, but if you were doing something else it could be very helpful.
