This depends on the point of view. I expect to find a rather high standards in Haskell programs than, say, Ruby, for exactly the same reasons you've mentioned and I think it's an awesome feature, quite the opposite to a mistake. And yes, I am a "real programmer" and don't use Haskell at work myself (for the run-time performance reasons).
