-Template.hs:9:5: warning: [-Wmissing-monadfail-instances (in -Wcompat)]
- • Could not deduce (Control.Monad.Fail.MonadFail m)
- arising from the failable pattern ‘Just _’
- (this will become an error in a future GHC release)
- from the context: Monad m
- bound by the type signature for:
- monadFail :: forall (m :: * -> *) a. Monad m => m a
- at Template.hs:7:1-27
- Possible fix:
- add (Control.Monad.Fail.MonadFail m) to the context of
- the type signature for:
- monadFail :: forall (m :: * -> *) a. Monad m => m a
- • In a stmt of a 'do' block: Just _ <- undefined
- In the expression:
- do Just _ <- undefined
- undefined
- In an equation for ‘monadFail’:
- monadFail
- = do Just _ <- undefined
- undefined
