	The core of what the system is about is:

	- Having rough/flexible data strutures
	- Performing transformations on those data structures
	- Finding the core "must be correct" structures we want to reason about
	- Defining and naming those structures with relative precision,
	hardening them into definite declarations
	- Validating and verifying that input and output conform to those
	now-hardened structures.

	Thank you! These are great.

	Here's my gut investigation so far:

	The multi-item vs. single-item distinction is a really good point. In
	things like GMail, it's a multi-item system, there's a breakdown between:

	- the items you can select
	- a small set of operations you can apply to the items in bulk
