Taking off my review manager hat for a moment, I have a few thoughts/questions:

- I agree with @DevAndArtist's comment from the pitch thread:

- I still don't like the restriction that the ability to synthesize a memberwise init depends on the relative ordering of properties and their `accesses` clauses. Since `accesses` clauses can only refer to stored properties there's no chance of cycle, and IMO we should synthesize a memberwise init with the parameters matching source order but with properties initialized in dependency order (ties broken by source order).

- To Jordan's point above:

ETA:

- Does invoking the setter of a stored property in an `init` accessor (can you do this?) invoke the `didSet` observer? IIRC the current rule is that setters called inside `init` never call `didSet`, seems like we should extend that to `init` accessors.

I noted myself as weakly against this direction in the pitch, but I think one thing to consider with the new syntax that puts the `initializes` and `accesses` clauses _outside_ the `init` clause, a future direction which allows combining the `init` and `set` accessors is IMO significantly more awkward (it's not clear that `initializes` really only applies to the `init` and not the `set`). I guess you could just learn this, but it's something to consider...
