In a way the @ prefix wasn't necessary either as the original poster said: "if I had ops" in my opinion he was assuming that he was an op in a channel. So therefore he wouldn't get "NickName" to type "!opme" if he knew that he wasn't an op. If you know what I mean, probably don't but hey!
As for the (100 isin $level($address($nick,3))). There is no explanation for me using it. As you said "it was just as good" Therefore either one would do, so lets just leave it at that eh .
