I really like the idea of Reason & the community is pretty nice from my experience. At the same time, installing it on Windows is a huge pain. Windows 10 was feasible. Windows 7 (because Enterprises can't ever upgrade) is really hard to install it in my experience. I understand this has more to do with OCaml on Windows (which is odd since F# is very similar to OCaml). By the way, I should also mention that F# has Fable which compiles F# to JavaScript. It would be great if the Reason & Fable communities worked together if you're not already.
