 PHP has a syntactical issue with a construct like the following:

 {{{
 $value = return_array_fun()[$key];
 }}}

 where return_array_fun() is a function returning an array as output.

 One is forced to rewrite it as

 {{{
 $temp_array = return_array_fun();
 $value = $temp_array[$key];
 }}}

 It would be nice to have a function in WordPress that makes this simple.
 Here's the one-liner:

 {{{
  /**
    * Get the value of an element in an array
    */
   function array_get_value( $array, $key ) {
           return $array[$key];
   }
 }}}

 I didn't create a separate diff file for this.
