Answer 1

I would typecast the int and string datatypes automatically with no complaint (because they could be easy to mix up), but for something like a resource or object it could be a useful feature to notify the programmer of an error.

I would also set up the notification code in its own function so things wouldn't get so repetitive. Anyways, Good luck!
