For example, the following function predicate whether a Church numeral n is 0: IsZero := λn.n (λx.False) True. When n is 0, (λx.False) is not applied, and IsZero directly returns True. When n is positive, (λx.False) is applied for n times. (λx.False) always return False, so IsZero returns False. binging with babish garlic peeler
