Unless is the opposite of L<if|Template::Liquid::Tag::If>. The block is rendered
I<unless> the conditon is true.

=head1 Synopsis

    {% unless value == 5 %}
        Doesn't equal five!
    {% else %}
        Aww... it does equal five.
    {% endunless %}

Since L<unless|Template::Liquid::Tag::Unless> is simply a subclass, see the list of
bugs for L<if|Template::Liquid::Tag::If>. They basically apply here too.
