 WordPress has, since quite long time, helper functions like
 `__return_true` and
 [[https://developer.wordpress.org/?s=__return_&post_type%5B%5D=wp-parser-
 function|others]].

 These are useful to be added to filters.

 Now that minimum PHP version is 5.6 we could have something like:

 {{{#!php
 <?php
 function __return_value($value) {
     return static function () use ($value) {
         return $value;
     }
 }

 function __return_value_by_ref($value) {
     return static function () use (&$value) {
         return $value;
     }
 }
 }}}

 which would quite useful in many places, at least as useful as the other
 mentioned functions that are already there.
