async/await with ES6 Generators & Promises

This vanilla ES6 function async allows code to yield (i.e. await) the asynchronous result of any Promise within. The usage is almost identical to ES7's async/await keywords.

async/await control flow is promising because it allows the programmer to reason linearly about complex asynchronous code. It also has the benefit of unifying traditionally disparate synchronous and asynchronous error handling code into one try/catch block.

This is expository code for the purpose of learning ES6. It is not 100% robust. If you want to use this style of code in the real world you might want to explore a well-tested library like co, task.js or use async/await with Babel. Also take a look at the official async/await draft section on desugaring.

The primary goal is to swap command and option.

The secondary goal is to remap Caps Lock to Control.

The tertiary goal is to share modifier keys across keyboards, so you can emacs with two keyboards.

The following instructions are good as of 2016-08-24, for OS X El Capitan 10.11.6.
  Mac OS Sierra broke Seil support; Seil instructs us to consider Karabiner Elements.
  But when Karabiner Elements swaps command and option, it does it for all keyboards;
  meaning the native keyboard also gets its command and option swapped, which is bad!

Promises as EventEmitters

I was trying to understand JavaScript Promises by using various libraries (bluebird, when, Q) and other async approaches.

I read the spec, some blog posts, and looked through some code. I learned how to
