Hallo to all,
Just curious after reading a posting on the internet.
Is somebody using Fortress in combination with Haskell ( GHC) in a
parallel setup.

Not to my knowledge. The Fortress implementation is still at the
prototype stage; the prototype runs on the JVM, and JVM/Haskell
interoperability is known to be a bit tricky. In general there are
substantial challenges to integrating two languages with independent
garbage-collected run time systems. Add in independent notions of
transactional memory, rather different thread scheduling models, and
so forth and the problem becomes trickier still.
That said, there is certainly at least one Haskell programmer writing
Fortress code (I wrote much of the library and some of the code
examples in the language implementation). We've certainly looked to
the FP community for inspiration in many aspects of the language. My
favorite example: Fortress generators are essentially build forms for
algebras in the Boom hierarchy, and we're effectively doing library-
driven foldr/build elimination (except in this algebra it's map-
reduce/build instead).
