The Foo part can participate in type inference

use std::ops::Deref;

fn main() {
    let a = Default::default();
    let b = String::deref(&a);
}

Maybe we ought to preserve Foo::deref anyway though as unlike .deref() it does provide more information to the reader than the equivalent &*, what type is being deref'd can be confusing

[Centri3]

Ah yeah, so this will still cause an error on that as well. The best path forward then would probably be to preserve it as you said, and specify that it excludes Foo::deref like done with d.unwrap().deref()

[llogiq]

Thanks @Alexendoo for taking on the review, and thanks @Centri3 for pushing this forward!
