Feature request: Return types on anonymous functions

[adamsmd]

Is your feature request related to a problem? Please describe.

There might already be an option for this, but I haven't been able to find one. If there is, please let me know.

ocamlformat moves the return types of anonymous functions after the body of the function, but I want it to put the type after the arguments of the function

Here is what I want:

fun (x : int) : int -> some_large_computation

Here is what ocamlformat produces:

fun (x : int) -> (some_large_computation : int)

You can test this with:

echo 'fun (x: int): int -> some_large_computation' | ocamlformat --impl --enable-outside-detected-project -

Describe the solution you'd like

I'd like an option that makes ocamlformat produces the first and not the second.
