#15354: QuantifiedConstraints not fully described in manual -------------------------------------+------------------------------------- Reporter: goldfire | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: 8.6.1 Component: Documentation | Version: 8.5 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): Yes there's some overlap (with the existing productions) in the grammar. I considered having rules for all combinations of with and without foralls and context (for each of the two forms of head) leading to six productions instead of two, but I decided against. The grammar isn't trying to tell you which extension you are using, just what forms are legal. I don't feel strongly; it does not seem v important. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15354#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
