This is not an issue about 8.2.2 per se, but 8.2 changes in general: Recent discussions on Haskell Cafe showed serious problems with Emacs' haskell-mode due to some ad hoc changes like https://phabricator.haskell.org/D3651. Related GitHub issues: https://github.com/haskell/haskell-mode/issues/1553 https://github.com/haskell/haskell-mode/issues/1496 It should be noted that the output of GHC(i) is actually part of GHC's interface, so in this light, there have been some breaking changes, probably unintended, but nevertheless. So my question is: Is there a chance to revert some of these ad hoc changes and/or add some flags to get the old behavior back? I guess that Emacs + haskell-mode is one of the most important IDEs, so it would be a pity to worsen the situation there. I'm quite aware that it is very late in the release cycle, but it would be extremely nice if there was something which can be done. In the future it might make sense to co-operate with the haskell-mode team a bit more, perhaps adding some tests regarding the required output format etc. to GHC's test suite. Cheers, S.
