Implementing default with default - recursion

Description

Hey, this is probably a pretty silly feature request, but this tripped me up way more than it should have.

Normally, if you try to implement Default and use ..Default::default(), it'll give you the following warning:
recursive call site [unconditional_recursion].

However, if you add any function call, this will no longer happen.

pub struct Test {
    pub a: String,
    pub b: i32,
}

impl Default for Test {
    fn default() -> Self {
        let test = "test".to_string();
        Self {
            a: test,
            ..Default::default() // No compiler warning!
        }
    }
}

In retrospect, this is exceptionally obvious. But my intuitive thought when I was writing that line was that the remaining fields would be implemented with Default, not that it would refer to the struct itself. Rust Analyzer even suggests using it... not that that's any excuse either, but I lost a lot of time to this particular footgun 😞

Start by reviewing the Rust example and the related rust-clippy issue #103 to understand the requested recursion warning. The payload names no repository files or tests; done should include detecting this Default implementation pattern and emitting an appropriate warning without being bypassed by an unrelated function call.
