src/: ~21 capital-Foreign comments the case-sensitive verify grep missed (Foreign-class→Runtime-class, Foreign path→Runtime path, Foreign decls→Extern decls, FOREIGN function→extern function) across calls/inst/ffi_objc/jni_descriptor/emit_llvm/ c_import/lower.*/ops. src 'foreign' now = ONLY the hash_foreign token + 4 rejection messages (9.0-delete targets). examples/*.sx comments → extern/runtime-class (1219 stdout regen; KEPT 1176). docs/inline-asm-design + debugger purged. Comments only — no build impact. 9.0 ratified: DELETE hash_foreign token next.

// M1.3 — `obj.class` accessor on Obj-C pointers.
|
|
//
|
|
// Any Obj-C-class pointer (runtime or sx-defined) can be probed
|
|
// for its runtime class object via `obj.class`. Lowers to
|
|
// `object_getClass(obj)`. Returns `Class` (alias for *void —
|
|
// parameterized `Class(T)` covariance is M1.1.b).
|
|
//
|
|
// Verifies both shapes:
|
|
// 1. (*SxFoo).class — sx-defined class. Returns the SxFoo Class.
|
|
// 2. (*NSObject).class — runtime class via stdlib. Returns NSObject's
|
|
// Class.
