Possible to use async without with_context everywhere?

[rex-remind101]

I'm wondering if it's possible to have a series of awaits in the function a span is created without every single async call requiring .with_context(ctx) appended?

Example here https://github.com/open-telemetry/opentelemetry-rust/blob/482772f2317e242e6b98bfe04ed42e4dac8cf77b/examples/async/src/main.rs#L52

Could consider creating a crate with macros to help here, similar to how tracing-attributes allows you to have a more ergonomic async API.
