does carbon support type erasure for Comparable?

[fililili]

hi, all. I found Swift supports such usage for type erasure. It's interesting for me and I am looking for other language that supports same usage. So, Is such usage supported by carbon, too? thanks.

func selfc<T: Comparable>(_ a: T) -> Bool {
    print(a)
    return a < a;
}

/* cannot compile
func selfca(_ a: any Comparable) -> Bool {
    return a < a;
}
*/

struct Person: Comparable {
    var name: String
    var age: Int
    
    static func < (lhs: Person, rhs: Person) -> Bool {
        return lhs.age < rhs.age
    }
}
let person1 = Person(name: "Alice", age: 30)
let person2 = Person(name: "Bob", age: 25)

var cs : [any Comparable] = [person1, person2, 1, 2.4]
for c in cs {
    print(selfc(c))
}

Yes, what you're describing is what Carbon calls checked generics. See https://github.com/carbon-language/carbon-lang/tree/trunk/docs/design/generics for the design.
