Discussion on: That's so Rusty! Fearless concurrency

[sxci]

fn main() {
    let generic_greeting = String::from("Good day,");
    let print_greeting = |name| println!("{} {}!", generic_greeting, name);
    let person = String::from("Crab");
    print_greeting(&person);
    println!("Can I use generic greeting? {}", generic_greeting);
    println!("Can I use person {}", person);
}

this is ok
