I'm not entirely sure why this is getting downvoted so much other than possibly tone that offends the FP community (I'm sympathetic since the evergreen Perl is dying! stuff causes a twitch in me for down voting as well). The biggest reason I have dismissed functional programming languages is that they appear to believe that all problems are pure (which in some cases are entirely appropriate to assume) but then have to exempt themselves from their own paradigms to deal with reality. What I mean is essentially what Kant declares with the categorical imperative, "wish it universal." FP paradigms always seem to have to exempt themselves from this in order to work with a lot of real-world problems. Of course, I may just be old and not entirely grokking the real abstract ideas of functional programming.
