pub const ALIASES: &[(&str, &str)];Expand description
Spellings that are not typos, and what each one means here.
A distance search cannot find these. cls is one edit from cols and two from class, so
the nearest name is the wrong one — and cls= is what
docs/01 §1.3’s sketch writes, faithfully,
because the original conversation did. It is therefore the first thing a reader arriving from
that page will type, and the first suggestion they should get.
