#5012: haskell 98 program does not typecheck when compiled with -XTypeFamilies ----------------------------------------+----------------------------------- Reporter: jcpetruzza | Owner: Type: bug | Status: closed Priority: normal | Milestone: Component: Compiler (Type checker) | Version: 7.0.2 Resolution: invalid | Keywords: Testcase: | Blockedby: Difficulty: | Os: Unknown/Multiple Blocking: | Architecture: Unknown/Multiple Failure: GHC rejects valid program | ----------------------------------------+-----------------------------------
Comment(by simonpj): You can also use `-XNoMonoLocalBinds` (after the `-XTypeFamilies`). With high probability it will work just fine; but the flag imposes some compromises on the type checker, which is why it's off by default.
