Go would be amazing if it didn't allow dumb mistakes such as:

    type Human struct {
        Name string
        MaybeHasCat *Cat
    }

    type Cat struct {
        Name string
    }

    func main() {
        h := Human{}
        h.MaybeHasCat.Name = "Taffy" 
    }

And boom. Null pointer exception because MaybeHasCat is null. The fact that go doesn't let you define an optional type is such a pain. A lot of newcomers while getting trained up fall for this bug.

edit: updating to add the pointer i missed. also adding a playground link: https://go.dev/play/p/izcod8xF7ZQ
