// The object language parsing is handling by a separate standalone Elm
// application in the ObjectLanguage module, which has two ports:
//
// * `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.
