tcfail165.hs:19:23: error:
• Couldn't match expected type ‘forall a. Show a => a -> String’
with actual type ‘b0 -> String’
• In the second argument of ‘putMVar’, namely
‘(show :: forall b. Show b => b -> String)’
In a stmt of a 'do' block:
putMVar var (show :: forall b. Show b => b -> String)
In the expression:
do var <- newEmptyMVar ::
IO (MVar (forall a. Show a => a -> String))
putMVar var (show :: forall b. Show b => b -> String)
