// A reserved/builtin type-name spelling is rejected as the NAME of EVERY
// type-introducing `::` declaration too — struct, enum, union, error-set, and
// a typed constant — not just `:=` / value-const / function names (those are
// examples/1140). Each is a declaration-name binding site: a bare reserved
// spelling there mis-classifies and is rejected, exactly like `i2 := …`. The
// backtick escape (`` `i2 :: struct{…} ``, examples/0154) is the only way to
// spell these names in handwritten sx; `#import c` foreign decls stay exempt
// (examples/1220).
//
// Regression (issue 0089 — attempt-4: 0076 holds across every decl kind).
// Expected: one error per declaration, each caret ON the declared name; exit 1.
