  1. Suggest adding Result return type for associated method in E0277.

    For following:
    
    ```rust
    struct A;
    impl A {
        fn test4(&self) {
            let mut _file = File::create("foo.txt")?;
            //~^ ERROR the `?` operator can only be used in a method
        }
    ```
    Suggest:
    
    ```rust
    impl A {
        fn test4(&self) -> Result<(), Box<dyn std::error::Error>> {
            let mut _file = File::create("foo.txt")?;
            //~^ ERROR the `?` operator can only be used in a method
    
        Ok(())
        }
    }
    ```
