#9378: Make unknown LANGUAGE pragmas a warning, not an error -------------------------------------+------------------------------------- Reporter: goldfire | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.8.2 Resolution: | Keywords: Operating System: | Architecture: Unknown/Multiple Unknown/Multiple | Difficulty: Unknown Type of failure: | Blocked By: None/Unknown | Related Tickets: Test Case: | Blocking: | Differential Revisions: | -------------------------------------+------------------------------------- Comment (by hvr): Well, then there's the other thing that turning such a pragma into warning is in conflict with the [https://www.haskell.org/onlinereport/haskell2010/haskellch12.html#x19-191000... Haskell 2010 Report] stating explicitly that:
If a Haskell implementation does not recognize or support a particular language feature that a source file requests (or cannot support the combination of language features requested), any attempt to compile or otherwise use that file with that Haskell implementation **must fail with an error**.
