Don't get me wrong, I wasn't attacking OCalm, nothing against it, I'm curious about Functional Programming, I've yet to try them for serious projects. It's just not in my toolset currently. Also I'm trying to maintain a rule whereby I don't install software I don't use frequently. OCaml might be nice, but I'm rather unlikely to use it as much as I use the other programming languages in my system. I appreciate that this solution is offered as a web service.
