[Haskell] GHC/ Fortress -Parallel Computing

Hallo Jan-Willem,
Hallo all,

Thanks for the clarification first.
And coming to your statement 
> We've certainly looked to

 is there anything planned to advice programmers what use Haskell, to code in Fortress.
The document what I have in mind in this direction is a Introduction in Lisp for Python programmer.

Any feedback welcome
