For cases 3 and 4 C<$options{value}> defaults to C<id> and

+In addition to pure keys/method you can also provide coderefs as I<value_sub>

+title.
+
+Lastly a joint coderef I<value_title_sub> may be provided, which in turn takes
+precedence over each individual sub. It will only be called once for each

+If the option C<with_empty> is set then an empty element (value
+C<undef>) will be used as the first element. The title to display for
+this element can be set with the option C<empty_title> and defaults to

+C<method => 'raw'> will just include the given text as is. I was too lazy to
+implement C<include> properly.
+
+Also an C<if> attribute is supported, so that tabs can be suppressed based on
+some occasion. In this case the supplied block won't even get processed, and
+the resulting tab will get ignored by C<tabbed>:
