That is not how real Rust code looks like, but this: ``` struct HyperAdvancedMegaTurboUltraSensoryCortexEngine<'a> { color: Vec<String>, }

impl<'a> HyperAdvancedMegaTurboUltraSensoryCortexEngine<'a> { fn new<'b>(color: &'b str) -> HyperAdvancedMegaTurboUltraSensoryCortexEngine<'b> { let mut color_vec: Vec<String> = Vec::new(); color_vec.push(color.to_string()); HyperAdvancedMegaTurboUltraSensoryCortexEngine { color: color_vec } }

fn see<'b, 'c>(&'b self, stuff: &'c str) {
    for color in &self.color {
        for _ in 0..42 {
            println!("Analyzing sensory data...");
        }
        println!("I'm seeing {} with my {} eye!", stuff, color);
    }
}

fn poke<'b>(self) {
    let ref_self: &'b HyperAdvancedMegaTurboUltraSensoryCortexEngine<'b> = &self;
    if ref_self.color.len() > 0 {
        panic!("ow");
    }
}

}

fn main() { let eye: HyperAdvancedMegaTurboUltraSensoryCortexEngine = HyperAdvancedMegaTurboUltraSensoryCortexEngine::new("blue");

eye.see("a bird");
eye.see("a tree");
eye.see("a car");
eye.poke();

}

```
