I wonder if it would be inviting disaster to suggest that "quoting"
an expression always force string context rather than integer.  So

	$x = 0;

	print "Just another " unless $x;
	print "Perl hacker," if "$x";

would yield output that makes Randal happy. :-)

Right now 0 and "0" both evaluate false, while 00 is false and "00" true.
Of course you can 'say what you mean' and use ($x ne "") instead, which
might even be better programming practice in many cases...
