Perl's canonical false value is a dualvar that is 0 when used as a number and '' when used as a string.

$ perl -MData::Dumper -le 'print Dumper(1 == 0)'
$VAR1 = '';

With the upcoming perl 5.38 release, the boolean values will be tracked and Data::Dumper will represent their boolean nature:

$ perl -MData::Dumper -le 'print Dumper(1 == 0)'
$VAR1 = !!0;

So maybe the docs should be fixed here
