#14320: Brackets change meaning of value-constructor type -------------------------------------+------------------------------------- Reporter: nr | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.2.1 (Type checker) | Keywords: GADT, | Operating System: Linux existential type | Architecture: x86_64 | Type of failure: GHC rejects (amd64) | valid program Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- Some legacy code from GHC 7.x does not compile under 8.0 or 8.2. The issue seems to be that I have wrapped brackets around the type of a value constructor, and 8.x does not want to see those brackets. To try to learn if this change was deliberate, I have searched the release notes. Found nothing. I am hoping this is an actual bug, as I would hope to be able to wrap any type or term in brackets without changing its meaning (except of course for fixity). -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14320 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
