This is a little bit contrived but it demonstrates the problem.
```
def good_exception():
raise Exception('something bad happened')
def bad_exception():
return next(iter([]))
def good(n):
return good_exception() + n
def bad(n):
return n - bad_exception()
import traceback
try:
max(good(i) for i in range(4)) # desirable behaviour
except:
traceback.print_exc()
try:
min(bad(i) for i in range(7)) # unhelpful error message
except:
traceback.print_exc()
```
