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
