The NET ecosystem is too heavily built for C#. The documentation is hard to use, and nearly non existent for F#. I looked at it before I started digging into Ocaml. I interact with Linux far more than anything else, I think Ocaml is just going to be more useful to me, more often.
I really admire Don Syme though. He's one of the most intelligent people in software, by my reckoning. Literally a brilliant genius in a field littered with mediocre hacks that work real hard to ship things. He's a real legend.
Thanks for the suggestion though. Maybe some folks will come across it for the first time now. It's a well designed syntax, and has some really interesting features. Units of Measure in particular is a really cool thing I've needed before, I usually just use data classes and decorators in python to do a lookup, and just pay the performance penalty. It's neat to have that info at compile time for free.
Jane St are a hedge fund doing some seriously heavy lifting in OCaml land, and they sometimes write up really interesting stuff they've done. It's less tutorial-like than fsharp for fun and profit, though.
