how does simply putting a piece of logic in your code and print out an error meesage when a variable match a certain value prove something in Perl is either true nor false? this is simply impossible in Perl because you can never code a 3-way logic.
use strict; use warnings;
my $test = 0;
($test) ? print "\$test exists"
: ($test > 0) ? print "\$test greater then zero"
: ($test < 0) ? print "\$test less then zero"
: print "\$test is zero";undef $test;
(undef, $test) ? print "\$test is defined"
: print "\$test is undefined";__END__
But I was asked not to confuse... So ignore this posting...
