#11721: GADT-syntax data constructors don't work well with TypeApplications -------------------------------------+------------------------------------- Reporter: goldfire | Owner: goldfire Type: bug | Status: new Priority: normal | Milestone: 8.2.1 Component: Compiler | Version: 8.1 Resolution: | Keywords: | TypeApplications 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 Richard Eisenberg <eir@…>): In [changeset:"35e937973f61a7e5534ecd0b1c67111cd82d4238/ghc" 35e93797/ghc]: {{{ #!CommitTicketReference repository="ghc" revision="35e937973f61a7e5534ecd0b1c67111cd82d4238" Track specified/invisible more carefully. In particular, this allows correct tracking of specified/invisible for variables in Haskell98 data constructors and in pattern synonyms. GADT-syntax constructors are harder, and are left until #11721. This was all inspired by Simon's comments to my fix for #11512, which this subsumes. Test case: ghci/scripts/TypeAppData [skip ci] (The test case fails because of an unrelated problem fixed in the next commit.) }}} -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/11721#comment:4> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler
