PolyKinds and mutually recursive modules

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.
