print $foo;
print -$foo;

    Yeah, I'm not sure anyone has ever used that feature. It snuck in there because certain linguists love to write their linguistic booleans as +feature and -feature, plus there was some resonance with Tk's -foo syntax. But we're probably breaking that too in favor of something more natively Perlish.
