 I received a PHP notice "Array to string conversion" that led me to the
 current_action() function in class-wp-list-table.php.

 This function can return an array as a valid value. For example this
 request will return an array:

 http://localhost/site/?action[]=1&action[]=2

 But in this case:

 PHPDoc is incorrect. Should be:

 {{{
 @return string|false|array
 }}}

 or/and

 this may break some of the scripts that use this function. simply because
 they use the result value as a string. Possible solution: add an
 additional check: IF array THAN take only the first value of the result.

 Thanks!
