<pkgmetadata> <maintainer type="project"> <email>haskell@gentoo.org</email> <name>Gentoo Haskell</name> </maintainer> <longdescription> This package contains the "Control.Monad.Fail" module providing the <https://prime.haskell.org/wiki/Libraries/Proposals/MonadFail MonadFail> class that became available in <https://hackage.haskell.org/package/base-4.9.0.0 base-4.9.0.0> for older @base@ package versions. This package turns into an empty package when used with GHC versions which already provide the "Control.Monad.Fail" module to make way for GHC's own "Control.Monad.Fail" module. </longdescription> </pkgmetadata>
