I'm curious what your users think this will do

print("start listing")
with ignore(ZeroDivisionError):
     for i in range(0, 4):
         inv = 1 / i
         print("1 over {} is {}".format(i, inv))
print("finished")

I think there's a decent chance I'd get it wrong if I was scanning 
through code with that construct in the midst of it.
