Comment (by dd32):

 The PHP Warning is specifically:
 > wp-includes/class-wp-taxonomy.php:430 - call_user_func() expects
 parameter 1 to be a valid callback, no array or string given

 Adding a `use( $args )` to the closure callback will fix it, if that's
 acceptable for core usage, otherwise the callback will need to run
 something like `$args = get_taxonomy( $taxonomy )`.
