I now have a paragraph summarizing the "narrowing of scope" benefit,
though not worded as a rebuttal of a concern. Eli's concern is mainly
that this can be abused, which everything can; should I include
something about that? Brett's issue is with the colon. I'll write up a
paragraph or two of reasoning as to why that was selected, possibly
tomorrow, but the main reason is simply that nobody came up with a
compelling argument in favour of any other. Hardly the most epic tale
