#8993: Fold NullaryTypeClasses into MPTC -------------------------------------+------------------------------------ Reporter: owst | Owner: Type: bug | Status: patch Priority: normal | Milestone: Component: Compiler | Version: 7.8.2 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Unknown/Multiple Type of failure: None/Unknown | Difficulty: Unknown Test Case: | Blocked By: Blocking: | Related Tickets: -------------------------------------+------------------------------------ Comment (by simonpj): I'm fine with this, but I think the error message could be better. "Too many args" is better than "Invalid number of args". It would be easy to generate the same messages as before, by passing `arity` to `classArityErr`.
