In Perl 6 we can't just test a string for truth to determine if it has a value. The string "0" will test as false even though it has a value. Instead we must test for length. |

<lang perl6>my $s = ''; |
|||
say 'String is empty' unless $s.chars; |
|||
say 'String is not empty' if $s.chars;</lang> |
