A column whose format is one read of a record's column and nothing else —
`"score": "{/src.score}"`, `"score": "{s.score}"` with `s` bound to `/src`, or `"a": "{p}"`
beside `{place as p}` in its own record — is that column: it takes the column's datatype and
is null where the column is, and a struct field tagged `src.score` is nil there. A `datatype` of its own types the
column's values where they prove it, and one restating the datatype it takes is refused.
Any other read renders the column's text, a null as `""`.
