| Subject: strange difference between old and hierachical module names
| 
| Hi,
| 
| I am trying to compile some modules with old imports
| such "import MonadFix". These modules compile fine
| with GHC 6.0 latest RPM, and also on CVS source tree
| 6.1 somewhere from july.
| 
| However, the file below does NOT get through with GHC HEAD.
| I get ...
| 
| > Compiling Foo              ( Foo.hs, interpreted )
| >
| > Foo.hs:13: `mfix' is not a (visible) method of class `MonadFix'
| > Failed, modules loaded: none.
| 
| If I use the new "import Control.Monad.Fix" instead of MonadFix,
| everything works fine. This is a bit strange because
| for most old imports there is no such problem.
| Seems to be something special going on with MonadFix.
| 
| Thanks,
| Ralf
