Import associated item of generic trait and confusing "type annotations needed"

Code

#![feature(import_trait_associated_functions)]

trait X<Y> {
    fn foo() -> String;
}

use X::foo;

fn test() {
    let _ = foo();
}

Current output

error[E0283]: type annotations needed
  --> src/lib.rs:10:13
   |
10 |     let _ = foo();
   |             ^^^^^ cannot infer type
   |
   = note: the type must implement `X<_>`

For more information about this error, try `rustc --explain E0283`.

Desired output

Either the import should be disallowed, or the error should suggest using a trait-qualified function name.

Rationale and extra context

I don't know if there is any way to use an imported associated item of a generic trait?

No response

Reproduce the example in src/lib.rs with the nightly toolchain and read the diagnostic around E0283, then review tracking issue #134691 for the feature's intended behavior. Done means the import is rejected or the resulting error suggests a trait-qualified function name for the generic associated item.
