An implementation is not required to respect any pragma, although
#13921: LANGUAGE pragma is accepted in module body -------------------------------------+------------------------------------- Reporter: bgamari | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.0.1 (Parser) | 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 bgamari): I suppose it's arguably okay to treat the `LANGUAGE` pragma in this context as unknown and therefore ignore it. From the Report, pragmas that are not recognised by the implementation should be ignored. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13921#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
