Binding ImplicitParams in lambda results in parse error
ImplicitParams
currently do not play well with lambdas :(
Steps to reproduce
Create a file Foo.hs
with the following content:
{-# LANGUAGE ImplicitParams #-}
import Control.Monad
foo :: (?bar :: Int) => IO ()
foo = print ?bar
main = do
forM_ [1..3] $ \ ?bar -> foo
Expected result
$ runhaskell Foo.hs
1
2
3
Actual result
$ runhaskell Foo.hs
Foo.hs:9:21: Parse error in pattern: ?bar
