Replace GOTO with structured code

Use exceptions

Imho exceptions aren't much better. They are essentially a goto where

you don't know where you're going,
you can send data with it (including context) and
you can guarantee execution of code if needed (I've never really worked with gotos but I assume there is no equivalent to finally).

2 & 3 are nice and probably the reason why they are still used today, but 1 is terrible for understanding bigger systems.
