unintuitive error message about unbalanced parentheses
A minimal test case is as follows:
testFunc file = do
let file1 = file) return file1
If you try to load it, you will get:
- ..\test.hs:111:2:
The last statement in a 'do' construct must be an expression
This error message is kind of unfriendly, and probably only GHC authors know how a mismatched parenthesis can lead to such an error message.
