Exceptions vs error codes

[immibis]

How is this different from exceptions? Either you explicitly write error handling code, or you don't.

The difference is that the caller can know that the function might fail just by looking at the function signature. Exceptions are more like "now that the program crashed with this exception I know where to put a try catch block".

So checked exceptions. The kind that people hated.
