Whew! <- The sigh of relief after reading comments here and realizing that I'm not the only one preferring the standard style of writing Python instead of this "functional"(??) style... I get that Optional return values can force the programmer to handle errors without resorting to exceptions, but I can't help but wonder whether the first example with all those `bind_optional` ... is just Objective-C's nil messaging in fancy disguise... FWIW in Objective C this is exactly what one writes (even if those functions can return nil): credit = user.get_balance().credit_amount() if credit > 0: discount_program = choose_discount(credit) I'm not sure what's so "functional" about it though.
