The biggest problém with Opam and OCaml on Windows is that most of the packages won't work. Officially, Opam does not support Windows at all, that is going to be included with 2.2 (which is still in alpha AFAIK)

I always thought of Opam as the best feature of OCaml (especially compared to Haskell with two no-working package managers - and no, Nix is a problém, not a solution either).
Yeah in fairness at least it has one package manager and it does seem well designed even if it doesn't actually work properly half the time. So it is fixable!
Which is more than you can say for Python and C++.
