| Summary | 0000123: typeclass instance clause type mix. | ||||
| Description | In a typeclass instance, when the clause of a predicate is defined directly in the instance, qualifying certain types result in the compiler mixing up types. See the attached example, where simply adding :_ to a type makes the compiler complain about wrong typing; while doing the same but with the predicate defined outside the instance (via pred(...) is) works perfectly fine. | ||||
