AGRA ruling (attempt 4): `` `name `` is THE LITERAL identifier `name`, usable in EVERY position — the backtick only means "treat this token as a plain identifier, never the reserved keyword/type", and is never part of the name's text. - Raw in TYPE position is now VALID (reverses attempt-2 "raw is not a type"): `parseTypeExpr` emits a raw `type_expr`; `TypeResolver.resolveNamed` gains a `skip_builtin` flag (threaded from `te.is_raw` via lower.zig + type_bridge) so a `` `s2 `` reference resolves to a `` `s2 ``-declared type (struct/enum/union/alias), else a normal "unknown type 's2'" error (reportIfUnknownType skips the builtin exemption when raw). Bare `s2` in type position stays the builtin int. - Every declaration-name site is is_raw-exemptible: `is_raw` added to TypeExpr + StructDecl/EnumDecl/UnionDecl/ErrorSetDecl/ProtocolDecl/ForeignClassDecl/UfcsAlias/ NamespaceDecl/ImportDecl/CImportDecl/LibraryDecl; parser threads name_is_raw to every decl parse fn; namespace imports carry it through imports.addNamespace. Typed-const path (`` `s2 : s64 : 5 ``) now threads name_span+is_raw (fixes the 1:1-caret bug). - Check<->exemption made structurally symmetric: checkBindingName/checkDeclName take is_raw as a REQUIRED argument and skip inside the check, so no call site can validate a name without honoring the exemption (the desync cause of prior rounds). - Bare reserved-name declarations of every kind still error (0076 preserved); `#import c` foreign names stay auto-raw + bare-callable. specs.md + readme.md updated to the universal model. issue 0089 RESOLVED banner rewritten. Examples: replace 1139 (raw-not-a-type) with 0154 (raw type reference); add 0155 (typed const + union tag) and 1141 (bare type-decl negatives). Gate: zig build + zig build test + run_examples (426 passed, 0 failed).

// 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 `s2 := …`. The
|
|
// backtick escape (`` `s2 :: 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.
