Notes

The structopt crate will probably be merged into the clap crate at some point.
[email protected] was released today, and folded the structopt-derive crate into its core. I wonder if serde and failure will be able to do the same in the future.
configure and structopt seem a bit at odds with each other. configure works through env vars, while structopt works through flags. The main use case I'm seeing for configure right now is to toggle debug logging. Perhaps this is because I'm not writing network services for production use, yet.

this.local.todos.map(todo => this.cache.get(Todo, Todo.id(todo)).render(todo))

self-managing identity, because we can't embed inside diffing algo
identity check needs to be static, creating a new instance can't be the solution
LRU cache GC
one liner for creation + use
no imports for management
no singletons
no extensions of state if possible

	// This version gives a "cannot move out of borrowed content error"
	let ref fd = &self.fd.unwrap();

	// But I guess that's fair game. Docs say it "moves" content, which
	// is not what we want. How about expect?
	let ref fd = &self.fd.expect("Invalid state: no fd found in Sync::Write");

	// Nope, also doesn't work. This is the only version that works fine.
	let fd = match &self.fd {
	&Some(ref fd) => fd,

	module.exports = class Emitter {
	constructor () {
	this.listeners = {}
	}

	on (event, listener) {
	if (!this.listeners[event]) this.listeners[event] = []
	this.listeners[event].push(listener)
	}

	var { App } = require('choo')

	var app = new App()
	app.store(import('./stores/my-store'))
	app.render('body')
