How to download and view legacy documentation from Apple (no need to sign in to your dev account)

1. Download the docset index XML.
2. Find the docset you want (there are some with URL https://apple.com/none.dmg; ignore them - you will find them again further down the file with a working URL).
3. Download the dmg. It's probably around a gigabyte or so.
4. "Install" the .pkg file somewhere on your disk. If you don't trust the installer, do it manually:
   1. Find the largest file, named Payload, and extract it using The Unarchiver.
   2. This creates a new, even larger file, probably named Payload-1.
   3. Extract Payload-1 using The Unarchiver.
5. After many minutes of extracting, we have our .docset file.

A composable pattern for pure state machines with effects

State machines are everywhere in interactive systems, but they're rarely defined clearly and explicitly. Given some big blob of code including implicit state machines, which transitions are possible and under what conditions? What effects take place on what transitions?

There are existing design patterns for state machines, but all the patterns I've seen complect side effects with the structure of the state machine itself. Instances of these patterns are difficult to test without mocking, and they end up with more dependencies. Worse, the classic patterns compose poorly: hierarchical state machines are typically not straightforward extensions. The functional programming world has solutions, but they don't transpose neatly enough to be broadly usable in mainstream languages.

Here I present a composable pattern for pure state machiness with effects,
