TODO: add summary and links here

I am not sure I understand the term "materializing storage"? Edit: ok, I think I get it now, but it seems this database terminology means putting data on disk?

FYI, I think this is in a good-enough shape for more review.

There are a few fairly narrow TODOs, but they're about filling in overview information that is already discussed in detail elsewhere or cleaning up alternatives considered.

I have preserved as an appendix a fairly old writeup of use cases observed throughout C++ that end up being relevant background for the particular design proposed. I've not done much to review or update this write-up, as it isn't directly a part of the proposal. I'm also happy to remove it if it is more of a distraction than utility, or happy to do some updates to it to try and connect it more thoroughly with the proposal but I'd like suggestions for what would be useful there before investing the time.

I'll try to wrap up the TODOs left in the next day or so.
