IMO it should be clear from the top of a for loop how many iterations it will run. A goto randomly inside the loop is akin to a side effect in a function. Sure it might be the easiest solution you can think of, and might even generate optimal code, but it's less readable and forces future maintainers to exert more effort to understand the code. |

How would you implement something simple like a lookup in an array? From this argument even a break in a normal for-loop would be bad since I wouldn't know anymore how many iterations it will take. So if you have a nested loop and a "goto end_outer_loop" that's perfectly fine.
