I was going to say this was documentated behavior since I have known this since version 6; however, when I went to check to see if you could escape the '&' in a quick test Oracle ignored the '&' in a comment. So on version 8.1.7 it appears SQLPlus now is aware of when '&' variables are declared in commented out lines.
