Need check for multiple applicable items in scope

[philberty]

struct Foo<A> {
    a: A,
}

impl Foo<isize> {
    fn test() -> i32 {
        123
    }

    fn bar(self) -> isize {
        self.a
    }
}

impl Foo<char> {
    fn test() -> i32 {
        123
    }
    
    fn bar(self) -> char {
        self.a
    }
}

fn main() {
    let a:i32 = Foo::test();
}

This error only occurs when the compiler needs to resolve the PathExpr because it can resolve to multiple items.
