Phantom types in ReasonML

Introduction

"A phantom type is a parametrised type whose parameters do not all appear on the right-hand side of its definition..." Haskell Wiki, PhantomType

The following write-up is intended as an introduction into using phantom types in ReasonML.

Taking a look at the above definition from the Haskell wiki, it states that phantom types are parametrised types where not all parameters appear on the right-hand side. Let's try to see if we can implement a similar example as in said wiki.

let recv = (client, maxlen) => {
  let bytes = Bytes.create(maxlen);
  let len = Unix.recv(client, bytes, 0, maxlen, []);
  Bytes.sub_string(bytes, 0, len)
};

let parse_top = top => {
  let parts = Str.split(Str.regexp("[ \t]+"), top);
  switch (parts) {
