Expand 'yield' in internal macro calls.

Resolves #27.

As in the title.

I can't replicate the test failures locally. It seems the test CI is simply running cargo test +stable --all-features, which passes on my machine with flying colors. What am I missing?

I'm not sure if it's a trybuild bug or a rustc bug, (sometimes) test results in CI may differ from those run locally...

Thanks! This looks good to me aside from a few nits.

[SergioBenitez]

Cool. This looks good to me, too!

[SergioBenitez]

What's keeping this from being merged?

[taiki-e]

Sorry, I forgot about this, I'll review it again and merge it if it looks good.

I noticed this breaks code that has another async stream macro inside the macro.

use tokio::select;
use async_stream::{stream, try_stream};
use futures_util::stream::StreamExt;

async fn do_stuff_async() {}

let s = stream! {
    select! {
        _ = do_stuff_async() => {
            let another_s = try_stream! {
                yield;
            };
            let _: Result<(), ()> = Box::pin(another_s).next().await.unwrap();
        },
        else => {},
    }
    yield
};

[SergioBenitez]

Good catch! Should be good to go.

[SergioBenitez]

Fixed the rustfmt issue.

Thanks!

Any chance this can find its way into a release? I'm currently exporting stream from my fork but would love to depend on upstream instead. This would also make it possible to publish a release that depends on the macro.

Filed #60 for next release.

Published in v0.3.2.

Awesome, awesome, awesome. Thank you!
