Move `yield` expressions behind their own feature gate In order to make progress with the `iter!` macro (e.g. in #137725), we need `yield` expressions to be available without the `coroutines` feature. This PR moves `yield` to be guarded by the `yield_expr` feature so that we can stabilize that independently (or at least, concurrently with the `iter_macro` feature). Note that once `yield` is stable, it will still be an error to use `yield` expressions outside something like a generator or coroutine, and these features remain unstable. r? `@oli-obk` |
