[curry] Haskell compatibility

Hi!

I've read that Curry is a super set of Haskell, except for the type classes. But some Curry implementations do also include Haskell type classes.

Does that mean, that Haskell code can easily be used inside Curry programs? Like C in C++? Is it possible to use all those Haskell libraries in Curry?

Or, if not, is it very easy to port Haskell to Curry?

Cheers Volker
