Can't find List.cons mentioned in List docs page

[farskid]

According to https://reasonml.github.io/docs/en/list-and-array, spread syntax for appending items to a list is just an alternative to List.cons. I couldn't find any reference to such a method name List.cons in API docs.

Is it a real thing or just a typo of List.concat?

I was looking for the same thing, and I don't think List.cons exists in the Reason/BuckleScript/Belt libraries in the mentioned form. I think they are referring to the List.cons from the OCaml (standard?) library, like here: https://caml.inria.fr/pub/docs/manual-ocaml/libref/List.html

It sounds like this page is saying [h, ...t] is the Reason equivalent of List.cons, but it could be more clear.
