It's been a few years since I've touched OCaml - the ecosystem just wasn't what I wanted - but the core language is still my favorite.

And the best way I can describe why is that my code generally ends up with a few heavy functions that do too much; I can fix it once I notice it, but that's the direction my code tends to go in.

In my OCaml code, I would look for the big function and... just not find it. No single workhorse that does a lot - for some reason it was just easier for me to write good code.

Now I do Rust for side projects because I like the type system - but I would prefer OCaml.

I keep meaning to checkout F# though for all of these reasons.
