In the definition of gmapQr, extra effort is needed. We use a higher-order accumulation trick to mediate between left-associative constructor application vs. right-associative binary operation (e.g., @(:)@). When the query is meant to compute a value -of type @r@, then the result type withing generic folding is @r -> r@. +of type @r@, then the result type within generic folding is @r -> r@. So the result of folding is a function to which we finally pass the right unit. |
