An idea for Fractal to support classes packaged with themes to overriding/interrupt inheritance of Fractal plugin classes

gistfile1.txt

// An idea for a way to always look in the child theme first, even if you're in a Fractal (parent theme) class. 
// Every time you use would require_once for a file with a class you're about to extend, use fractal_require(), instead.

function fractal_require( $file_name_without_extension ) {
  $overriding_file = get_stylesheet_directory() . "/fractal/$file_name_without_extension.php";
	if ( file_exists( $overriding_file ) ) {
		require_once $overriding_file;
		return true;
	}
	// At this point, fall back to just require_once, and assume in the same directory
	require_once "$file_name_without_extension.php";
	return false;
}
