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. http://en.wikipedia.org/wiki/Fortress_programming_language

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). -Jan-Willem Maessen Project Fortress Sun Microsystems

Thanks for any feedback
