/**
 * Inline-expectations test for the store/load/delete/parameter
 * classification predicates on the new-CFG facade.
 *
 * Each tag fires when the corresponding predicate (`isLoad`,
 * `isStore`, `isDelete`, `isParameter`, `isAugLoad`, `isAugStore`)
 * holds on the canonical CFG node wrapping a `Py::Name` with the
 * given identifier.
 *
 * For subscript / attribute stores the tag fires on the Subscript /
 * Attribute node itself, with `value` set to the rightmost identifier
 * (the attribute name for `Attribute`, the index expression's textual
 * form for `Subscript`).
