I assume this is because runWriterT is a record selector of WriterT and could (or should?) be imported as: {{{ import Control.Monad.Trans.Writer (WriterT(runWriterT)) }}} Since I used runWriterT like a regular function I did not care about its record selector feature. -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/8149> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

When I pull it up in `gdb`, there are warnings pertaining to missing object files expected to be in a `/Users/ian` directory. There's never been an `ian` user on my machine, so I suspect that's an artifact from whomever built the binary.

It can be accepted in any position of an identifier except the first, where Haskell requires the character to be either upper/title-case (conid) or lower (varid). isLetter x && not (isUpper x) does not imply isLower(x). -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/8068> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

[GHC] #9126: -ddump-to-file in TcRnMonad.lhs
by GHC 20 Nov '14

#9126: -ddump-to-file in TcRnMonad.lhs ------------------------------------+------------------------------------- Reporter: GregWeber | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.8.2 Keywords: | Operating System: Unknown/Multiple Architecture: Unknown/Multiple | Type of failure: None/Unknown Difficulty: Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | ------------------------------------+------------------------------------- As part of #8624, the first thing we realized is -ddump-to-file wasn't being respected. This is against HEAD, but I would really like to merge it to 7.8.3 if that is ok. I tested this with -ddump-tc and -ddump-splices. -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/9126> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler
