I am in love with types and type systems. They are, quite probably,
my favorite concept in the world. Most of us mere
mortals use types as a way to make sure we aren't writing

It's finally time to start looking at types. As I mentioned, I want
to take an approach that draws a variety of examples from the real
world - I'd like to talk about examples from real programming

### Inference Rules and the Study of Programming Languages
In this post, I will talk about _inference rules_, particularly in the field
of programming language theory. The first question to get out of the way is

//
// * `parseString` requests a string to be parsed
// * `parsedString` returns the parsed string, or null

// We want there to be a single global ObjectLanguage object, but it works
// on a "subscription" model (we have to give a callback to its port).
// Configure this callback to invoke `resolve` functions from a list,
// so that callers can just get a promise. This way we aren't continuously
// registering more and more handlers for each parsed string, and we can
// use a convenient promise API.
