I'm not claiming F# is not viable without the module system, I'm saying F# is not a drop-in replacement for OCaml. There are good reasons people might prefer OCaml. I that that's a reasonable response to this comment:

> I don't understand the Reason hype when F# / Fable already offers this

My only point is that there are good reasons people would prefer ReasonML/OCaml over F#. I never claimed there were no reasons other people might prefer F#.
