It's becoming more common to see "Functional Programming in X". Why don't we use functional languages like oCaml or Haskell more often? Are we making the jump in two steps instead of one? I've never written more than a few lines of either so I can't tell if something "better" is waiting for me in functional land.
Why are there so very few programs written in say, haskell, that you actually want to use?
This is a serious question that I haven't found the answer for. Around here people suggest pandoc, shellcheck and sometimes the xmonad window manager as pretty much the full list of things you can install, use and hack on written in haskell whose purpose isn't writing haskell code.
Given the popularity of haskell amongst hackers and the various claims about its benefits and strengths, the fact this list is so small (if it's larger and I'm missing a bunch - please DO let me know, I want to play with them and hack on them!) Is something I have difficulty reconciling with haskell being a useful general purpose programming language. Maybe they're being written now and they're on their way? But haskell has been around for more than a few years now. Maybe haskell hackers just mostly hate open source & free software unless it's GHC or a general purpose library? Seems unlikely. So maybe something else I don't yet understand. It is puzzling when I don't code in the language fluently enough to understand its weaknesses as opposed to my own in coding in the language and it's a point the many lovers of haskell never seem to address other than with extreme defensiveness which kind of misses the point of the question.
