create_function() deprecated in widget.php on line 169

I keep getting the following warning in my PHP error log:

PHP Deprecated: Function create_function() is deprecated in /home/elsiecar/public_html/wp-content/plugins/wp-youtube-lyte/widget.php on line 169

It does appear that create_function() is deprecated in PHP 7.2. The elegant thing to do would, I think, be to use a proper anonymous function, but those aren’t supported before PHP 5.3, and WordPress tries to be backwards compatible to PHP 5.2.4.

Perhaps you might replace

add_action('widgets_init', create_function('', 'return register_widget("WYLWidget");'));

with

function lyte_register_widget() {
register_widget('WYLWidget');
}

add_action('widgets_init', 'lyte_register_widget');
