Thank you, your post was most encouraging! I think I'll have to presume that the adept Haskell devs are mostly developing and not popularizing that much of their advancements.
well, they do whatever they have to do to pay the bills! I think a lot of these tool chains, or fragments thereof, are going to be open sourced eventually, but all engineering (open or not) is being paid for by someone (at least indirectly). So a lot of these tools are only going to be make that move once the authors can "pay" for the time to do so. ('cause life is more than just software i'm told!)
You can talk with a lot of people doing numerical computingy things in haskell on the #numerical-haskell channel on freenode.
