Leaving OCaml
So...I think a decent choice to make here is to switch from OCaml to F#. You'll get almost all of the benefits and most of the drawbacks go away. And for the most part, you can directly translate the code from OCaml to F#.<p>The big reason to not use F# vs OCaml tends to come down to the lack of functors... but it looks like your current codebase might not be using them much.
