module FizzBuzz | |
-- Dependently-typed FizzBuzz, about 5 years late to the party. | |
-- A specification of the problem. Each constructor tells the conditions | |
-- under which it can be applied, and the "auto" keyword means that proof | |
-- search will be used in the context where they are applied to fill them | |
-- out. For instance, applying `N` to some Nat fails unless there's a proof in | |
-- scope that the argument meets the criteria. | |
