=item C<action $method, @args>

Call the function with the name C<$method> on C<$self> with arguments

C<@args>. Returns the return value of the actual function

called. Useful for chaining (see above).

=item C<action_if $condition, $method, @args>

Call the function with the name C<$method> on C<$self> with arguments

C<@args> if C<$condition> is trueish. Does nothing otherwise.

Returns the return value of the actual function called if

C<$condition> is trueish and C<$self> otherwise. Useful for chaining

(see above).

This function is equivalent to the following:

  if ($condition) {

    $obj->$method(@args);

  }

But it is easier to integrate into a method call chain, e.g.:

  $js->html('#content', $html)

     ->action_if($item->is_flagged, 'toggleClass', '#marker', 'flagged')

     ->render($self);
