[Haskell-cafe] Equality constraints in type families

[Tom Schrijvers]

> could you please help me to clear up this confusion?-)

Let me summarize :-)

The current design for type functions with result kinds other than *
(e.g. * -> *) has not gotten very far yet. We are currently stabilizing 
the ordinary * type functions, and writing the story up. When that's done 
we can properly focus on this issue and consider different design choices.

Cheers,

Tom
