Code

I tried this code:

https://github.com/gotham-rs/gotham/tree/3da82b63e36db81f73f0d88b7610a3979c62289a/examples/handlers/simple_async_handlers_await

I expected to see this happen: Code compiles (as it does on stable: https://github.com/gotham-rs/gotham/actions/runs/3873554934/jobs/6603712754)

Instead, this happened: Code fails to compile (on beta: https://github.com/gotham-rs/gotham/actions/runs/3873554934/jobs/6603712995 and nightly: https://github.com/gotham-rs/gotham/actions/runs/3873554934/jobs/6603713263)

Version it worked on

It most recently worked on: 1.66.0 (69f9c33 2022-12-12)

Version with regression

1.67.0-beta.6 (51b0345 2022-12-31) and rustc 1.68.0-nightly (cc47b06 2023-01-08)
