And you know, that's totally fair. I'm not a mathematician so my perspective is limited only to producing production software. I'm simply relating my own experience in the hope that people will stop judging Haskell as a "research language" with little to no industrial value.

That's the funny thing about researchers, some seem extremely obstinate (I suppose in many ways that's a required attribute otherwise they might give up). I wonder if this is why we still have Fortran code around...
