WooCommerce - Change login redirect

gistfile1.txt

/*
 * goes in theme functions.php or a custom plugin
 *
 * By default login goes to my account
 **/
add_filter('woocommerce_login_widget_redirect', 'custom_login_redirect');

function custom_login_redirect( $redirect_to ) {
     $redirect_to = 'http://anypage.com';
}

It would be better:

/**
 * goes in theme functions.php or a custom plugin
 *
 * By default login goes to my account
 */
add_filter('woocommerce_login_widget_redirect', 'custom_login_redirect');

function custom_login_redirect( $redirect_to ) {
    return 'http://anypage.com';
}

How about redirecting to last visited page?
