 PHP 5.5's [http://us2.php.net/array_column array_column()] has a neat
 third argument for specifying a field to use as the key for the new array.
 Patch adds a third optional argument to wp_list_pluck() that mimics that
 behavior.

 Current functionality is this:

 {{{
 wp_list_pluck( get_posts( ), 'post_title' );
 }}}

 which returns an array like

 {{{
 Array
 (
     [0] => Hello World!
     [1] => Markup: HTML Tags and Formatting
     [2] => Markup: Image Alignment
     [3] => Markup: Text Alignment
     [4] => Markup: Title With Special Characters
 ~`!@#$%^&*()-_=+{}[]/;:'"?,.>
 )
 }}}

 With the patch, you could specify a field to use as the new keys, so
 {{{
 wp_list_pluck( get_posts( ), 'post_title', 'ID' );
 }}}
 would return
 {{{
 Array
 (
     [1699] => Hello World!
     [1178] => Markup: HTML Tags and Formatting
     [1177] => Markup: Image Alignment
     [1176] => Markup: Text Alignment
     [1174] => Markup: Title With Special Characters
 ~`!@#$%^&*()-_=+{}[]/;:'"?,.>
 )
 }}}
