#9888: Inconsistent type family resolution -------------------------------------+------------------------------------- Reporter: crockeea | Owner: Type: bug | Status: closed Priority: normal | Milestone: Component: Compiler | Version: 7.8.3 Resolution: duplicate | Keywords: Operating System: | Architecture: Unknown/Multiple Unknown/Multiple | Difficulty: Unknown Type of failure: GHC | Blocked By: rejects valid program | Related Tickets: Test Case: | Blocking: | Differential Revisions: | -------------------------------------+------------------------------------- Changes (by goldfire): * status: new => closed * resolution: => duplicate Comment: This looks like a duplicate of #9433. You've used `(==)` unapplied in your code, which is against the rules. It should be a syntax error, but instead, GHC attempts to make progress and falls flat on its face. Instead of `(TyCon2 (==))` in that spot, try `(:==$)`. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9888#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
