16895,wp_list_pluck cannot be used with arrays of references,dd32,,"Example code:

{{{
$one = array('num' => 1);
$two = array('num' => 2);
$input = array( &$one, &$two );

$nums = wp_list_pluck($input, 'num');

var_dump($nums, $input);
}}}

Example output:
{{{
array
  0 => &int 1
  1 => &int 2
array
  0 => &int 1
  1 => &int 2
}}}
Expected output:
{{{
array
  0 => int 1
  1 => int 2
array
  0 => &
    array
      'num' => int 1
  1 => &
    array
      'num' => int 2
}}}

This is caused by wp_list_pluck using the same variable name for the input array, and then overwriting it for the return.

One such real life example, is $wp_query->comments
