[Petal] A new modifier - logical or

[William McKee]

To the best of my knowledge, Petal does not provide a means of comparing 
two values. I hacked out an or: modifier which will return a true value if 
either of the values being compared are true. Thought I'd share the 
results for your comments/critiques/accolades <g>.

Have a good weekend,
William


			#
			# Do an OR comparison
			$Petal::Hash::MODIFIERS->{'or:'} = sub {
				my $hash = shift;
				my $args = shift;
				my ($arg1, $arg2) = split /\s/, $args;
				my $h1 = $hash->fetch($arg1);
				my $h2 = $hash->fetch($arg2);
				return ($h1 || $h2) ? 1:0;
			};
