Setup doesn't work properly / parse error on input 'import'

[Kostia R]

Hi. Not sure if I'm doing something wrong or not. I've created a very small repo where you can reproduce the error https://github.com/k-bx/docbug

The library code is as simple as:

module SomeLib where
-- $setup
-- let x = 1

import Data.Monoid

-- |
-- >>> add 1 1
-- 2
add :: Int -> Int -> Int
add x y = x + y

When I run stack test, I get:

$ stack test
docbug-0.1.0.0: test (suite: doctests)


src/SomeLib.hs:5:1: error: parse error on input ‘import’

Test suite failure for package docbug-0.1.0.0
    doctests:  exited with: ExitFailure 1
Logs printed to console

@k-bx This is a limitation of GHC's parser. The import has to go before the $setup-chunk.

@sol aha. Thank you!

I just stumbled upon this issue. Let us maybe make some appropriate corrections to README so that less people have to rediscover this ticket?

Yes, can you do this?
