[ANNOUNCE] GHC 8.6.1-alpha2 available
The GHC development team is pleased to announce the second alpha release leading up to GHC 8.6.1. The usual release artifacts are available from https://downloads.haskell.org/~ghc/8.6.1-alpha2 This alpha fixes many of the bugs reported in the first alpha and brings many of the core libraries to their (hopefully) final release versions. Unfortunately, the documentation troubles affecting the first alpha haven't quite been resolved in this release. Consequently you will again find there is no documentation uploaded. However, let us know if anything else is amiss. Thanks for your help! Cheers, - Ben

The GHC development team is pleased to announce the second alpha release leading up to GHC 8.6.1.
The following MVE uses the gitrev library ( http://hackage.haskell.org/package/gitrev ): $ cat Test.hs {-# LANGUAGE TemplateHaskell #-} module Main where import Development.GitRev commitInfo :: Maybe String commitInfo = case $(gitHash) of "UNKNOWN" -> Nothing hash -> Just hash main :: IO () main = print commitInfo The MVE compiles *without* warnings with different versions of GHC (e.g. 8.4.3) but with GHC 8.6.1-alpha2 I get the following warning: $ ghc Test.hs Test.hs:10:3: warning: [-Woverlapping-patterns] Pattern match is redundant In a case alternative: hash -> ... | 10 | hash -> Just hash | ^^^^^^^^^^^^^^^^^^^^^^ Linking Test ... Is it a bug or is it the expected behaviour? Best, -- Andrés
