Is there any workaround? or we can only use local builds for macOS?

Announced in Rust 1.64. https://blog.rust-lang.org/2022/09/22/Rust-1.64.0.html

It seems that we may also have to bump the cargo-udeps.

The latest cargo-udeps still requires a feature flag.

It’s available on our toolchain, but I’d prefer to bump our toolchain first.

IIRC storage have many unnecessary generics, but I’m not sure whether it’s related.

FYI, it seems that the bug is not related to `async` but to every nested `impl trait`. ```rust // err: concrete type differs fn bar() -> impl Iterator { std::iter::once((foo(),...

I've tested with the following codes: ```rust #![feature(type_alias_impl_trait)] trait Trait {} type TAIT = impl Trait; struct Bar; impl Trait for Bar {} fn foo() -> TAIT { Bar }...

What's the status of the issue? I'd like to take a try.
