// Phase 3 (FFI-linkage) — postfix `export` on an `#objc_class` aggregate, the
|
|
// explicit spelling for an sx-DEFINED runtime class (define + register). It is
|
|
// the same lowering as a bare `#objc_class("X") { … }` with no `#foreign`;
|
|
// `export` just makes the "I define this class" intent explicit (the dual of
|
|
// `extern` for "I reference an existing class"). Mirrors 1339's defined class.
