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,

GPG and git on macOS

Setup

No need for homebrew or anything like that. Works with https://www.git-tower.com and the command line.

1. Install https://gpgtools.org -- I'd suggest to do a customized install and deselect GPGMail.
2. Create or import a key -- see below for https://keybase.io
3. Run gpg --list-secret-keys and look for sec, use the key ID for the next step
4. Configure git to use GPG -- replace the key with the one from gpg --list-secret-keys

// We're going to try to build a collectionview layout engine that can serve up cells and supplementary views
// in a generic way. I haven't built this all the way to the collection view, and I don't konw what the real
// brief is, so there may be lots of gotchas here that don't work as desired, but it scopes out several ways
// to get a handle on the problem and how I'd at least probably start.

// Ultimately, this requires converting (Model, IndexPath) -> Cell and (Model, IndexPath) -> SupView. I'm 
// assuming that's the only feature of these factories.
