#4295: Review higher-rank and impredicative types -------------------------------------+------------------------------------- Reporter: simonpj | Owner: simonpj Type: task | Status: infoneeded Priority: normal | Milestone: 8.0.1 Component: Compiler (Type | Version: 6.12.3 checker) | Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by simonpj): No I have not looked at this for ages. Impredicativity is simply not a supported feature at the moment. If things are passing, then let them pass. If you have to change expect_broken to pass, then put a comment in the .hs file to point to this ticket and say that it might be wobbly because of impredicativity.
