[Yhc] Re-exports problem

[Dimitry Golubovsky]

Hi,

I am not sure if this is a known problem, but here's an example

There is a module which imports Ix (from haskell98) and has some
datatype deriving (Ix)

This module does not compile with the following message:

=================
Compiling Geometry         (
../../../home/dima/ext/workdirs/Fudgets/hsrc/utils/Geometry.hs )
yhc: -- during when renaming
Error: Identifier Data.Ix._tupleRange used at 7:35-7:36 is not defined.
Error: Identifier Data.Ix.inRange used at 7:35-7:36 is not defined.
Error: Identifier Data.Ix.range used at 7:35-7:36 is not defined.
Error: Type class Data.Ix.Ix used at 7:35-7:36 is not defined.
Error: Identifier Data.Ix._tupleIndex used at 7:35-7:36 is not defined.
Error: Identifier Data.Ix.index used at 7:35-7:36 is not defined.
=================

line 7 is where deriving (...., Ix ) is located.

If I import Data.Ix instead, everything compiles fine.

The Ix module from haskell98 is:

=================
module Ix ( Ix(range, index, inRange, rangeSize) ) where

import Data.Ix
=================

So, methods of the Ix class are not re-exported.

I am pretty much OK importing Data.Ix (anyway, Fudgets code needs to
be hierarchized, and I did something in this direction in the past),
but this may be a problem in Yhc.

Thanks.
