GHCi fails to `:reload` modules that require a plugin after turning on collection of type info with `:set +c`
Steps to reproduce
cabal init
Paste this into app/Main.hs
:
{-# OPTIONS_GHC -fplugin=MonadicBang #-}
module Main where
main :: IO ()
main = do print !(return 'a')
Add monadic-bang
to your *.cabal
file:
build-depends: base ^>=4.17.0.0, monadic-bang
$ cabal repl
ghci> :set +c
ghci> :r
Ok, one module loaded.
Collecting type info for 1 module(s) ...
Error while getting type info from Main: app/Main.hs:6:17: error:
Bang pattern in expression context: !(return 'a')
Did you mean to add a space after the '!'?
Expected behavior
Load the module.
Environment
- GHC version used: 9.4.4
