A.hs
{{{
{-# LANGUAGE PolyKinds #-}
module A where
import Test
class C (a :: k)
}}}
A.hs-boot
{{{
{-# LANGUAGE PolyKinds #-}
module A where
class C (a :: k)
}}}
B.hs
{{{
{-# LANGUAGE PolyKinds #-}
module Test where
import {-# SOURCE #-} A
}}}
Leads to:
{{{
A.hs-boot:5:7:
Class `C' has conflicting definitions in the module and its hs-boot
file
Main module: class C (k::BOX) (a::k) RecFlag Recursive
Boot file: class C (k::BOX) (a::k) RecFlag NonRecursive
}}}
The problem is not the `RecFlag`, it's the `k` kind variable that is
getting different uniques.
