#1544: Derived Read instances for recursive datatypes with infix constructors are too inefficient -------------------------------------+-------------------------------------- Reporter: jcpetruzza@… | Owner: Type: bug | Status: new Priority: normal | Milestone: 7.6.2 Component: Compiler | Version: 6.6.1 Keywords: | Os: Unknown/Multiple Architecture: Unknown/Multiple | Failure: Other Difficulty: Unknown | Testcase: Blockedby: | Blocking: Related: | -------------------------------------+-------------------------------------- Changes (by Doaitse): * failure: None/Unknown => Other Comment: When checking I noticed that the ChristmasTree package had problems compiling with the newer versions of GHC. I updated the package by adding some type annotations, and upgrading the cabal file. The fact that we did not get complaints thus far probably indicates that the problem is not perceived as a severe one by most users. I have no idea how many actually rely on this package or this technology. It would be nice if hackage would inform maintains about packages becoming obsolete due to upgrades of GHC or of packages it depends on, but that is another issue. -- Ticket URL: http://hackage.haskell.org/trac/ghc/ticket/1544#comment:29 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
