Comment (by scribu):

 Oh, and if you find yourself doing something like this:

 {{{
 foreach ( get_option( 'footer_sidebars' ) as $sidebar_id ) {
   add_action( 'wp_footer', function() use ( $sidebar_id ) {
     get_sidebar( 'footer' );
   } );
 }
 }}}

 you should consider refactoring your code so that it looks more like this:

 {{{
 add_action( 'wp_footer', function() {
   foreach ( get_option( 'footer_sidebars' ) as $sidebar_id ) {
     get_sidebar( $sidebar_id );
   }
 } );
 }}}
