data OverlapFlag Source
Constructors
| NoOverlap | This instance must not overlap another |
Fields | |
| OverlapOk | Silently ignore this instance if you find a more specific one that matches the constraint you are trying to resolve Example: constraint (Foo [Int]) instances (Foo [Int]) (Foo [a]) OverlapOk Since the second instance has the OverlapOk flag, the first instance will be chosen (otherwise its ambiguous which to choose) |
Fields | |
| Incoherent | Like OverlapOk, but also ignore this instance if it doesn't match the constraint you are trying to resolve, but could match if the type variables in the constraint were instantiated Example: constraint (Foo [b])
instances (Foo [Int]) Incoherent
(Foo [a])
Without the Incoherent flag, we'd complain that

Identifier occurrence information
Constructors
| NoOccInfo | There are many occurrences, or unknown occurences |
| IAmDead | Marks unused variables. Sometimes useful for lambda and case-bound variables. |
| OneOcc !InsideLam !OneBranch !InterestingCxt | Occurs exactly once, not inside a rule |
| IAmALoopBreaker !RulesOnly | This identifier breaks a loop of mutually recursive functions. The field marks whether it is only a loop breaker due to a reference in a rule |
