#8574: Failure to require FlexibleContexts ------------------------------------------------+-------------------------- Reporter: Feuerbach | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler (Parser) | Version: 7.6.3 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: GHC accepts invalid program | Unknown/Multiple Test Case: | Difficulty: Blocking: | Unknown | Blocked By: | Related Tickets: ------------------------------------------------+-------------------------- Comment (by monoidal): It seems this is valid Haskell 98: http://www.haskell.org/onlinereport/decls.html, section 4.1.3, the class is allowed to take `(tyvar atype1 ... atypen)` as an argument, and `atype` includes `Int`. But the [http://www.haskell.org/ghc/docs/7.6.3/html/users_guide/other- type-extensions.html documentation], section 7.8.2 claims Haskell 98 requires `(class (type-variable type-variable ...))` form. So I think this documentation should be changed to `(class (type-variable type type ...))`. Do you agree? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8574#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
