Callback issue

[Orio-nn]

When creating a function callback with the link below it throws an error

get('/', function() {
	echo "test";
});

However, if you change the link to literally anything else, it will work. This issue seems to only be present on / link.
The error message created is attached below.

Fatal error: Uncaught Error: Object of class Closure could not be converted to string in C:\xampp\htdocs\rbc\router.php:38 Stack trace: #0 C:\xampp\htdocs\rbc\router.php(6): route('/', Object(Closure)) #1 C:\xampp\htdocs\rbc\routes.php(14): get('/', Object(Closure)) #2 {main} thrown in C:\xampp\htdocs\rbc\router.php on line 38

This issue was tested with a brand new clone of this repo.

Callbacks are not intended to be used on the "/" route
