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.

Should be work with 0.18

Destructuring(or pattern matching) is a way used to extract data from a data structure(tuple, list, record) that mirros the construction. Compare to other languages, Elm support much less destructuring but let's see what it got !

Tuple

myTuple = ("A", "B", "C")
myNestedTuple = ("A", "B", "C", ("X", "Y", "Z"))

Quimby

Quimby is Walmart's service layer for mobile clients' configuration, CMS, a-b testing setup, and a few other sundry related services. It stitches together a constellation of data sources into a concise menu of API calls that mobile clients make to intialize and configure themselves.

Quimby is a REST service layer based upon the Gogo micro-service framework that we in turn built with Node.js, Hapi, Zookeeper, and Redis. Gogo is able to expose an array of web servers as a single host, and offers the ability to isolate tasks into smaller focused processes, emphasizing scalability and failure recovery. For example, a failure in any micro-service will not affect the life cycle of a request. Gogo also offers the additional features required to build distributed services with shared state, such as leader election.

Quimby components

• Penny (part of Gogo) - The micro-service router, responsible for pairing a request with a servicer

RaveJS goals

Step 1: Tame module loaders

The first thing that rave must do is simplify module loading: AMD, node, and ES6 modules. There's almost enough metadata in package.json and bower.json files to eliminate loader configuration. We can provide heuristics and conventions to fill-in the missing data.

If a developer wants to add a new capability to an application's loader, she
