Investigate symbols for metadata

[ssalbdivad]

E.g. could be used as a way to indicate that the keys of an object are exact inline:

import { exact } from "arktype";

const t = type({
  [exact]: "true",
});

Instead of using the separate metadata object?

It would be an alternate syntax for adding metadata to object types. There would still be a standard tuple expression/chained syntax as well.
