I personally find exceptions useful only when I want to jump many 
stack frames at once.

Overall I find them taxing because they add another possible 
'return' value to a function. Sometimes its documented, but 9 out 
of 10 times you'll find out at runtime.

Knowing all the possible error states of a function helps me 
enormously in avoiding surprises later on. While it might seem 
overwhelming at first, I find it liberating because the complete 
state space is right in front of me. I guess it is similar to the 
benefits of local reasoning.

Note I often write server programs. YMMV with e.g. batch programs.
