    1. There are other features you *could* actually polyfill, such as Array.of, Number.isNaN or Object.assign, because those don’t introduce syntax changes to the language – except that you shouldn’t.
    1. Polyfills are naughty as they patch native APIs, while ponyfills are pure and don't affect the environment.
    2. How are ponyfills better than polyfills? A polyfill is code that adds missing functionality by monkey patching an API. Unfortunately, it usually globally patches built-ins, which affects all code running in the environment. This is especially problematic when a polyfill is not fully spec compliant (which in some cases is impossible), as it could cause very hard to debug bugs and inconsistencies. Or when the spec for a new feature changes and your code depends on behavior that a module somewhere else in the dependency tree polyfills differently. In general, you should not modify API's you don't own.

    1. Instead of re-opening Ruby classes like that (I get involuntary twitches), for our little exercise we are going to invent another name

      IMHO, re-opening classes is okay. Certainly better than duplicating an entire core Ruby class and giving it a silly, less-meaningful name. (Though I'm not sure he actually intended people to use Lax instead of Lazy. I think he was just showing how easy it is to implement Lazy from scratch in Ruby.)

    1. allowing common connections to be made wirelessly

      This sounds a bit like “send” and “receive” in some (visual) programming languages and modular synths. But the fact that it’s based on common connections sounds quite clever.
