 *
 * These are the only bases for which the ring-construction notations
 * `\mathbb{Z}[\sqrt2]` (adjunction — `Adjoin`) and `\mathbb{Z}_n` /
 * `\mathbb{Z}/n\mathbb{Z}` (quotient — `QuotientRing`) are recognized. The
 * list is explicit rather than derived from the type of the operand: "is a
 * ring" is an algebraic property the type lattice does not model (a
 * `set<integer>` type is carried by `PositiveIntegers` too, which is not a
 * ring), and keeping the dispatch narrow leaves `At`/`Subscript` over every
 * other set-typed base exactly as it was.
