#14674: Deferring more levity polymorphism checks in indefinite backpack modules -------------------------------------+------------------------------------- Reporter: andrewthad | Owner: (none) Type: feature request | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.4.1-alpha1 Resolution: | Keywords: backpack 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 andrewthad): Another more simple solution to this problem would be to add a flag that could only be used with indefinite modules named `-fdefer-levity-check`. This would entirely disable the binder rule for indefinite modules where it was turned on. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14674#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
