Are there any OCaml's best practices?

There are many good practices that are general to functional languages, not specific to OCaml. For example, having the key data structure as the last argument is very useful when chaining calls. Using abstract types when possible is also a good idea. Both of these points are documented in the Elm design guidelines but they’re equally applicable to OCaml.

This one’s not especially widely agreed upon. The Base/Core guidelines specify putting the primary element as the first argument, though the use of labeled arguments provides some flexibility on argument order.
