Yes let this be a lesson... instead of writing stupid crazy expressions that you need the C standard in front of you to figure out, write TOTALLY UNAMBIGUOUS READABLE CODE and then you don't have to WORRY about it. This isn't PERL.
But that goes for Perl too! And this problem could still be useful for figuring out
other programmers' totally ambiguous unreadable code...
