I'm curious, does every else find this

    let persons = names
        .map(Person.init)
        .filter { $0.isValid }

easier to read than this?

    var persons: [Person] = []
    for name in names {
        let person = Person(name: name)
        if person.isValid {
            persons.append(person)
        }
    }

I understand and appreciate the value of compact code, but I find the first one harder to read. A lot of inferred/token based coding is harder for me to mentally parse.
