I agree, unless I use setjmp/longjmp for that. Besides error recovery, 
there are occasionally other times when we want to locally "return" to a 
common state and start "from the top" again. I find such uses very clear 
in their intent, and if commented well, not hard to follow at all - as 
long as there is not more than one "top" :)
