You did actually verify if I was right didn't you?

@ARGV=reverse @ARGV;
print reverse <>;

I actually verified that both my <> solution and your solution are wrong (it does reverse the order of the lines of the files, but preserves original filename order). The idea is that a double-negative makes a positive.

You were right that my solution had an error. You followed it up with a solution that also contained an error.

I also verified that my final solution works properly. Hope the confusion is settled. ;)
