This is an interesting setup, but I'm not sure I see why you need
it. If you know that, in a particular context, you want toy(x, 0) to
result in 42 instead of ZeroDivisionError, why not just define
safeToy(x, y):
try:
retVal = toy(x, y)
except ZeroDivisionError:
retVal = 42
return retVal
. . . and then call safeToy instead of toy in those contexts?
