But it is neither a keyword nor an identifier. It behaves more like:
SELECT 1 as one; A constant, which have no implied rules - mainly because
numbers don't have case. Which suggests adding some specific mention there
- and also probably need to bring up it and its "untyped" nature in the
syntax chapter, probably here:

Typo on my part, fixed.

I'm not totally against just letting this content be assumed to be learned
from elsewhere in the documentation but it also seems reasonable to
include. I'm going to leave it for now.
