<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE pkgmetadata SYSTEM "http://www.gentoo.org/dtd/metadata.dtd"> <pkgmetadata> <maintainer type="project"> <email>haskell@gentoo.org</email> <name>Gentoo Haskell</name> </maintainer> <longdescription> This package backports the "Control.Monad.Except" module from @mtl@ (if using @mtl-2.2.0.1@ or earlier), which reexports the @ExceptT@ monad transformer and the @MonadError@ class. This package should only be used if there is a need to use the @Control.Monad.Except@ module specifically. If you just want the @mtl@ class instances for @ExceptT@, use @transformers-compat@ instead, since @mtl-compat@ does nothing but reexport the instances from that package. Note that unlike how @mtl-2.2@ or later works, the "Control.Monad.Except" module defined in this package exports all of @ExceptT@'s monad class instances. Therefore, you may have to declare @import Control.Monad.Except ()@ at the top of your file to get all of the @ExceptT@ instances in scope. </longdescription> <upstream> <remote-id type="github">RyanGlScott/mtl-compat</remote-id> </upstream> </pkgmetadata>
