| 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. |
