I love how the CommonMark Spec has a test suite that's just a JSON array. It's really easy to test a library for compliance, and I've seen developers nerd-sniped into full compliance. https://spec.commonmark.org/0.31.2/spec.json

IPv6 adoption is approaching half! https://www.google.com/intl/en/ipv6/statistics.html shows 46% as of today.

`init` feels like an unhelpful name in OO. It doesn't give you an initial value, it initialises the instance that has already been created. Developers are often surprised that init doesn't return the instance, because they have a strong association with `new Foo()`. Perhaps `finish` would have been a less confusing name?
