LexiFi use OCaml on windows in the industrial environment (they even have a .Net integration), so the language is stable. Many packages are working fine on windows too. opam is building already I think, but is not yet stable, you could ask them on github tho. The right way to install ocaml is [1]. I don't think you can avoid cygwin completely since you need rsync and similar stuff for some packages, tho the produced binaries do not require cigwin. https://fdopen.github.io/opam-repository-mingw/ https://fdopen.github.io/opam-repository-mingw/
